Bonds is having 40% full priced items on their site. Posted this on OzBargain yesterday but just remembered that the site ships to NZ too. You'll need to spend AUD$100 to get free shipping, otherwise it's $15 delivery fee to NZ.
I highly recommend their 'Sporty Top' bra which has perforated cups to keep you cool and are very long-lasting, wash after wash. My first one has lasted over 1.5 years with weekly wear and wash.
