The New Zealand Breast Cancer Study

The overall aim of the study was to explore the relationship between health behaviours across the lifecourse and breast cancer risk in three ethnic groups - Māori, Pacific and non-Māori/non-Pacific.

The study took place between 2005-2009 and included 1,801 women diagnosed with breast cancer and 2,547 women who did not have breast cancer.  The age of the women who took part ranged from 23 to 95 years, with the average age being 57 years. The participants included 1,040 Māori women, 239 Pacific and 3,069 non-Māori/non-Pacific women. People took part from all around the country with a high proportion of women coming from the greater Auckland region (24%) and significant numbers also from Canterbury (12%), Wellington areas (11%), Waikato (9%), the Bay of Plenty (5%) and Otago (4%).
