New Zealand Bra Size Calculator & Converter
Calculate your New Zealand bra size using dress-size bands (NZ 8, 10, 12, 14…) and UK-style cup letters, convert instantly to AU, UK, US & EU — with sister sizes and Bendon, Farmers, Berlei NZ, Triumph NZ & Hannahs fit notes.
How to measure correctly
- Wear a non-padded bra or no bra for accurate readings.
- Underbust: wrap tape snugly around your ribcage directly under the bust. Keep tape parallel to the floor. Exhale and measure.
- Overbust: measure around the fullest part of your bust. Tape should be loose enough to slide a finger underneath.
- Stand naturally — don’t lift arms or lean forward. Both measurements in the same posture.
- Round to the nearest ½ inch (or 0.5 cm) for best accuracy.

What Is the New Zealand Bra Sizing System?
New Zealand bra sizing uses dress-size band numbers (NZ 6, 8, 10, 12, 14, 16, 18, 20…) paired with UK-style cup letters (A, B, C, D, DD, E, F, FF, G, GG, H) — identical to Australia. The NZ band is derived from your underbust measurement using a dress-size lookup: 68–72 cm underbust equals NZ 12, 73–77 cm equals NZ 14. Cup letters are identical to UK, AU, and Indian sizing — NZ DD = UK DD = AU DD. New Zealand brands Bendon, Berlei NZ, and Triumph NZ all follow this system, which is the same as the Australian system in every respect.
New Zealand bra sizing is the same system as Australia — dress-size bands paired with UK-style cup letters. A NZ 12C and an AU 12C are identical sizes. This shared standard makes sense given the close commercial ties between the two countries: most major lingerie brands operate across both markets using identical labelling, and NZ shoppers regularly purchase from Australian retailers like ASOS AU, The Iconic, and direct from Berlei, which operates in both markets.
The dress-size band is New Zealand’s most distinctive feature. Unlike the UK (which uses inches), the EU and European markets (which use centimetres), New Zealand uses the same even-number dress sizes as Australia — NZ 8, NZ 10, NZ 12 — derived from the underbust measurement through a lookup table. NZ 12 corresponds to a 68–72 cm underbust, the same as UK 34, EU 75, and AU 12.
New Zealand’s leading domestic brand is Bendon, founded in Auckland in 1947. Bendon is unique in that it is New Zealand’s only major homegrown lingerie brand with genuine international reach — sold across Australasia, the UK, and the US. Their sizing follows the NZ/AU dress-size standard precisely and is considered the reference brand for New Zealand bra fitting.
NZ 10 and NZ 12 are the most common New Zealand bra bands — equivalent to UK 32 and UK 34. NZ = AU in every respect.
NZ cup letters are identical to UK and Australian cups — A, B, C, D, DD, E, F, FF, G, GG, H.
- NZ bands are dress sizes: NZ 6, 8, 10, 12, 14, 16, 18, 20… — NOT centimetres or inches. NZ = AU exactly
- NZ 12 = AU 12 = UK 34 = US 34 = EU 75 — all the same underbust (68–72 cm)
- NZ cup letters are identical to UK and AU — NZ DD = UK DD = AU DD. No conversion needed for cups
- NZ 12E = UK 34E = AU 12E = US 34DDD = EU 75F — the most common international conversion example
- Bendon, Berlei NZ, Farmers, Triumph NZ — all use dress-size band notation identical to Australia
How to Measure Your New Zealand Bra Size
You need your underbust and overbust in either inches or centimetres. The calculator will match your underbust to the correct NZ dress-size band automatically.
Prepare correctly
Wear a non-padded bra or no bra. Stand naturally with arms relaxed. Bendon’s fitting guides specifically recommend measuring without a bra for maximum accuracy — the same guidance given by Berlei Australia and Bravissimo UK.
Measure your underbust
Wrap the tape snugly around your ribcage directly beneath your bust. Keep it parallel to the floor. Exhale fully and record. Your NZ band is looked up from your underbust: 58–62 cm = NZ 8, 63–67 cm = NZ 10, 68–72 cm = NZ 12, 73–77 cm = NZ 14, 78–82 cm = NZ 16, 83–87 cm = NZ 18, 88–92 cm = NZ 20.
Measure your overbust
Measure around the fullest point of your bust. Keep the tape horizontal and loose enough to slide one finger underneath. Record in inches or centimetres.
Calculate your NZ cup letter
Subtract underbust from overbust: 1 in / 2.5 cm = A, 2 in / 5 cm = B, 3 in / 7.5 cm = C, 4 in / 10 cm = D, 5 in / 12.5 cm = DD, 6 in / 15 cm = E, 7 in / 17.5 cm = F, 8 in / 20 cm = FF. NZ uses the same UK cup progression — each step is approximately one inch or 2.5 cm.
Combine to get your full NZ size
Your NZ size is the dress-size band plus the cup letter: NZ 12C, NZ 14DD, NZ 10E. The number is always an even dress size (typically 6–26) and the letter follows the UK cup alphabet.
Bendon stores across New Zealand offer free in-store bra fittings. Their fitting specialists are trained to the NZ/AU dress-size standard and are particularly skilled at identifying the most common New Zealand fitting error — wearing a band 2–4 sizes too large with a cup 2–3 letters too small. If you haven’t had a professional fitting recently, Bendon fitting sessions are one of the most accessible and accurate ways to verify your NZ size.

Many New Zealand shoppers assume their NZ 12 band is equivalent to a European size 12 garment. It is not. NZ 12 is a dress-size band corresponding to a 68–72 cm underbust — the same as UK 34, EU 75, and AU 12. European clothing size 12 varies by country and has no direct relationship to the NZ bra band number. The NZ bra band system uses dress-size numbers, but these numbers have a specific cm lookup table — they are not clothing measurements applied to lingerie.
What Are Sister Sizes in New Zealand Bras?
Sister sizes in the NZ system work identically to UK and AU — bands step by 2 NZ sizes and cups shift by one letter. NZ 12 → NZ 14 is equivalent to going from UK 34 → UK 36.
| NZ Size | AU / UK Equiv. | Band Feel | Cup Volume |
|---|---|---|---|
| NZ 12D | AU 12D / UK 34D | Tighter | Same as NZ 14C |
| NZ 14C | AU 14C / UK 36C | Standard | Your primary size |
| NZ 16B | AU 16B / UK 38B | Looser | Same as NZ 14C |

New Zealand Bra Brand Sizing Differences
All NZ brands use dress-size band notation with UK-style cup letters, but construction and range vary meaningfully.
Bendon NZ
New Zealand’s only major homegrown lingerie brand, founded in Auckland in 1947. Bendon’s sizing follows the NZ/AU dress-size standard precisely and their fit research is the most comprehensive of any New Zealand brand. Stocks NZ 8–22 and cups A–J in the full range. The reference brand for New Zealand bra fitting.
Fit: True to NZ size. Bendon is the Berlei of the New Zealand market — use it as your calibration brand when testing other NZ labels. Cups suit medium-projection breast shapes. Highly accurate band sizing.
Berlei NZ
Australian brand with strong New Zealand presence. Uses NZ/AU dress-size bands — identical sizing to their Australian product. Stocks NZ 8–20 and cups A–J. Berlei NZ and Berlei AU are the same product with the same sizing. Accurate band and cup grading across the full range.
Fit: True to NZ size. Berlei NZ cups suit medium-projection breast shapes. If you have a full, round, or projected breast shape, size up one cup. Band sizing is accurate and true to the NZ/AU standard.
Farmers NZ
New Zealand’s largest department store chain. Farmers stocks bras from multiple brands using NZ dress-size bands. Their own-label range stocks NZ 10–18 and cups A–D. Multi-brand offering includes Bendon, Triumph NZ, and Berlei NZ. In-store fittings available at selected locations.
Fit: Own-label bands run true to NZ. Multi-brand sizing varies by label — use the brand’s own size guide when buying branded bras from Farmers. Free in-store fitting sessions available at major Farmers stores.
Triumph NZ
German brand’s New Zealand market. Uses NZ/AU dress-size bands — same as their Australian product. Triumph NZ 12 = Triumph AU 12 = Triumph EU 75 = UK 34. Stocks NZ 8–20 and cups A–H. Best NZ market option for NZ F cup and above where domestic brands’ ranges can thin out.
Fit: True to NZ size. Note that Triumph NZ and Triumph EU use different band labelling for the same body — Triumph NZ 12 ≠ Triumph EU 12. Always check which market label applies when shopping Triumph online.
Hannahs NZ
New Zealand footwear chain that also stocks basics lingerie including bras. Uses NZ dress-size bands. Limited bra range — NZ 10–16 and cups A–D. Better suited for occasional purchases than primary bra shopping. Bands and cups run true to NZ standard in their range.
Fit: True to NZ band in their limited range. Cup coverage stops at D — shoppers in DD cup and above should look to Bendon, Berlei NZ, or international specialists. Available across New Zealand with wide store coverage.
Bravissimo UK (buying from NZ)
UK D+ specialist. Ships to New Zealand. Uses UK sizing — band numbers convert directly (UK 34 = NZ 12, UK 36 = NZ 14) and cup letters are identical. NZ E = UK E. A New Zealand shopper in NZ 14E would order UK 36E from Bravissimo with no conversion needed for the cup.
Fit tip: Convert your NZ band to UK: NZ 12 → UK 34, NZ 14 → UK 36. Keep your cup letter exactly — NZ and UK cups are the same. Bravissimo’s D+ range starts where most NZ retailers stop.
ASOS AU / The Iconic (buying from NZ)
Both platforms ship to New Zealand and stock a mix of AU/NZ-sized brands and UK-sized brands. AU/NZ-sized brands use dress-size bands. UK brands (Freya, Panache, Bravissimo sub-brands) use UK inch bands. AU 12 from Berlei and UK 34 from Freya are the same band — the size filter may mix them together.
Fit tip: Convert NZ band to UK before ordering UK brands: NZ 12 → UK 34, NZ 14 → UK 36. Cup letters are identical between NZ and UK — no conversion needed. Always check the product page size guide to confirm which system applies.
Victoria’s Secret US (buying from NZ)
Available online in New Zealand using US sizing. Band: NZ 12 = US 34, NZ 14 = US 36. Cup: NZ A–D = US A–D (identical). Above D: NZ DD = US DD, NZ E = US DDD, NZ F = US DDDD. VS does not stock above US DDD (= NZ E), limiting options for NZ F+ shoppers.
Conversion: NZ 12E → US 34DDD. NZ 14DD → US 36DD. US bands run slightly small — size up one US band if borderline.
Signs Your New Zealand Bra Size Is Wrong
Band size problems
- Band rides up at the back: band too big. Try one NZ size down, one cup up (e.g., NZ 14B → NZ 12C).
- Band digs in or leaves marks: band too small. Try one NZ size up, one cup down (e.g., NZ 12C → NZ 14B).
- Band pulls forward when arms are raised: band too loose. Tighten hooks or go down one NZ band size.
Cup size problems
- Spillover at top or sides: cup too small. Size up one cup letter (NZ 14C → NZ 14D).
- Gaping or wrinkling: cup too big. Size down one letter (NZ 14C → NZ 14B).
- Underwire on breast tissue instead of ribcage: cup too small. Size up immediately.
- Centre gore not flat against sternum: cup too small or wire too wide for breast spacing.
Bendon’s fitting research shows that the majority of New Zealand women are wearing an incorrectly sized bra. The most common error mirrors the global pattern: wearing an NZ band 2–4 sizes too large and a cup 2–3 letters too small. If you have never had a professional fitting, or haven’t measured in the last 12 months, your current NZ size is likely incorrect. Bendon’s free in-store fitting service is the most accessible first step to finding your accurate size.
Shopping International Brands as a New Zealand Shopper
Buying from Australian retailers (ASOS AU, The Iconic, Berlei AU)
NZ and AU sizing are identical. NZ 12E = AU 12E. No conversion needed — same band number, same cup letter. Shop from any Australian retailer in your exact NZ size with no adjustment required.
Buying from UK retailers (Bravissimo, ASOS UK, M&S)
NZ band to UK band: NZ 8 = UK 30, NZ 10 = UK 32, NZ 12 = UK 34, NZ 14 = UK 36, NZ 16 = UK 38, NZ 18 = UK 40. Cup letters are identical — NZ DD = UK DD, NZ E = UK E. Keep your cup letter exactly — only the band number needs converting. NZ 14E = UK 36E at Bravissimo.
Buying from US retailers (Victoria’s Secret, ThirdLove)
NZ band to US band is the same as NZ to UK: NZ 12 = US 34, NZ 14 = US 36. Cup: NZ A–D = US A–D (identical). Above D: NZ DD = US DD, NZ E = US DDD, NZ F = US DDDD. So NZ 12E = US 34DDD. US bands run small — size up one US band if borderline.
Buying from EU retailers (Triumph EU, Hunkemöller)
NZ band to EU: NZ 10 (63–67 cm) = EU 70, NZ 12 (68–72 cm) = EU 75, NZ 14 (73–77 cm) = EU 80. Cup: NZ DD = EU E, NZ E = EU F, NZ F = EU G. Add one cup letter when converting NZ to EU above DD. So NZ 12E = EU 75F at Triumph Germany.
When shopping on The Iconic or ASOS AU from New Zealand, check whether each brand uses NZ/AU dress-size bands or UK inch-based bands. New Zealand and Australian brands (Bendon, Berlei, Bonds) use NZ/AU numbering. UK brands (Freya, Panache, Bravissimo) use UK inch bands. The same size filter may return NZ 12 from Bendon and UK 34 from Freya — both the same band measurement — but the platform doesn’t always distinguish between the two systems. The product page’s size guide is the authoritative reference.

Frequently Asked Questions
New Zealand bra sizing uses dress-size band numbers (NZ 6, 8, 10, 12, 14, 16, 18, 20…) paired with UK-style cup letters (A, B, C, D, DD, E, F, FF, G). The NZ band is derived from your underbust measurement using a dress-size lookup — 68–72 cm underbust equals NZ 12. Cup letters are identical to UK and Australian sizing. Major NZ brands Bendon, Berlei NZ, Triumph NZ, Farmers, and Hannahs all follow this system.
Yes — completely identical. NZ 12C equals AU 12C. New Zealand and Australia use the same dress-size band numbers and the same UK-style cup letters. Most major brands (Berlei, Triumph, Bendon) operate across both markets with identical product labelling. Shopping from an Australian retailer in your NZ size requires no conversion whatsoever.
NZ 12 equals UK 34, US 34, and EU 75. All correspond to an underbust measurement of 68–72 cm. The NZ number 12 is a dress size — not a centimetre or inch measurement. NZ 12 = AU 12 = UK 34 = US 34 = EU 75 = FR 90. These are all the same band expressed in different national conventions. For cup letters, NZ and UK are identical — NZ 12E equals UK 34E with no conversion needed for the cup.
Yes — completely identical. NZ cup letters are exactly the same as UK cup letters: NZ A = UK A, NZ DD = UK DD, NZ E = UK E, NZ FF = UK FF. No conversion needed for cups when buying from UK brands. Convert only the band: NZ 12 = UK 34, NZ 14 = UK 36. So NZ 14E at Bendon is the same cup as UK 36E at Bravissimo — same band measurement, same cup letter, same volume.
NZ band to US band: NZ 8 = US 30, NZ 10 = US 32, NZ 12 = US 34, NZ 14 = US 36, NZ 16 = US 38. Cup: NZ A–D = US A–D (identical). Above D: NZ DD = US DD, NZ E = US DDD, NZ F = US DDDD, NZ FF = US G, NZ G = US H. So NZ 12E = US 34DDD. US bands run slightly small — size up one US band if borderline.
Based on Bendon’s fitting data, NZ 14B and NZ 14C are the most commonly purchased sizes in New Zealand. However, Bendon’s in-store fitting research suggests the true measured average is closer to NZ 14DD or NZ 12D when measured accurately — reflecting the same global pattern of women wearing bands too large and cups too small. Bendon estimates a majority of their customers are wearing an incorrectly sized bra before their first professional fitting.
Sister sizes step in 2 NZ band sizes and one cup letter. From NZ 14C, the sister sizes are NZ 12D (tighter band, same cup volume) and NZ 16B (looser band, same cup volume). These correspond directly to AU 14C, AU 12D, AU 16B and UK 36C, UK 34D, UK 38B. Particularly useful when shopping Bendon or Berlei NZ online where specific NZ sizes sell out during sales.
Measure your underbust in centimetres or inches. Match to the NZ band: 63–67 cm = NZ 10, 68–72 cm = NZ 12, 73–77 cm = NZ 14, 78–82 cm = NZ 16. Measure overbust loosely. Subtract: 1 in = A, 2 in = B, 3 in = C, 4 in = D, 5 in = DD, 6 in = E. Bendon recommends measuring without any bra. Our NZ calculator accepts both inches and centimetres.
This is common and expected. NZ bra band sizes are determined exclusively by your underbust measurement — not by your clothing dress size. A woman who wears NZ clothing size 14 may have an underbust of 68–72 cm (NZ 12 bra band) because her dress size is driven by her bust or hip measurement rather than her underbust. Always measure your underbust and use the lookup table rather than assuming your bra band matches your clothing size.
Bendon stocks through J cup in extended styles with bands through NZ 22. Berlei NZ extends through J cup as well. For sizes above NZ 22 or above F cup where local stock thins out, UK specialists like Bravissimo ship to New Zealand — and their cup letters are identical to NZ, so you simply convert the band (NZ 14 = UK 36) and keep the same cup letter.
Every six months at minimum, or after any weight change of 5 lb (2.5 kg) or more, pregnancy, breastfeeding, or starting or stopping hormonal contraception. Bendon’s fitting data suggests that most New Zealand women who remeasure after more than a year find their size has shifted by at least one band or cup step. Semi-annual home measurement and annual professional fitting at Bendon is the recommended routine.
Both platforms ship to New Zealand. Australian brands (Bendon, Berlei, Bonds) use NZ/AU dress-size bands. UK brands (Freya, Panache, Bravissimo sub-brands) use UK inch bands. When shopping UK brands: convert NZ 12 to UK 34, NZ 14 to UK 36 — and keep the same cup letter, since NZ and UK cups are identical. Check the brand’s individual size guide on the product page before ordering.
South Africa primarily follows UK sizing — inch-based band numbers and the same UK cup letters. South African 34C and New Zealand 12C are the same size (different band labelling, same underbust). Pacific markets including Fiji, Samoa, and Tonga tend to use either NZ/AU sizing (from Australasian imports) or UK sizing (from UK imports), depending on the brand. There is no standardised Pacific Island sizing convention separate from either the NZ/AU or UK system.
