They were delivered on behalf of the charity Uplift Project, which distributes donated bras around the Pacific to women who often struggle to get them.
Its Auckland coordinator, Kate Hargraves, said large shipments have also been shipped to Fiji and Samoa.
She said women in the Pacific have few means of getting bras, and they really appreciate what the Project's been able to deliver.
"When we get to go to the villages it's very very humbling. You meet the women and you see the excitement and really first-hand of what it means for them to have the bras. And where we can we send some good use underwear and swim wear. So it's a huge thing for the women there, and it's just very humbling."
