The number of women ringing the breast cancer helpline tripled following Angelina Jolie's decision to undergo a double mastectomy.
The increase matches an international trend that's been dubbed by media as the "Angelina effect".
The New Zealand Breast Cancer Foundation welcomed the attention Jolie has brought to the issue and said the actress had helped to raise awareness.
Foundation spokeswoman Adele Gautier said that in the first couple of weeks after news of Jolie's decision broke, inquiries to their contact centre and helpline increased three-fold.
Ms Gautier said a lot of women asked about their eligibility for the test to determine whether they had mutations in their BRCA genes that increase the chances of developing breast cancer by 60 per cent.
