Shopping for bras in New Zealand

New Zealand shares Australia's sizing: dress-number bands (a 12 band equals a US 34) with UK-style cup letters. Bendon, the historic local name, sizes true with strong T-shirt and everyday ranges.

Cross-Tasman online orders dominate the fuller-cup market; because AU and NZ sizing match, Australian charts apply directly with no conversion step.

Brands you will commonly see: Bendon, Rose & Thorne, AU imports.

New Zealand follows the same AU arithmetic as every other AU market, so the conversion chart lives in one place rather than being repeated: the full AU conversion chart. Sizes are written band first, then cup, as in 12DD.

Frequently asked questions

What bra sizing system does New Zealand use?
New Zealand primarily uses AU sizing conventions in mainstream retail, though imported brands can carry other systems' labels. The calculator above highlights your AU size and shows all 7 systems for imports.
Which bra brands are common in New Zealand?
Commonly available names include Bendon, Rose & Thorne, AU imports. Local availability shifts, and each brand's own centimeter chart beats any converted label when they disagree.
What is a US 34DD in New Zealand sizing?
A US 34DD is a 12DD in New Zealand. The same bra is a UK 34DD and an EU 75E, because the cup ladders diverge after D.
Do I add inches to my underbust measurement in New Zealand?
No. The old habit of adding four or five inches was written for non-stretch fabric and produces a band about two sizes too loose on a modern elastic one. Measure snug and level, and use that number directly, whichever system the label uses.
