The number of women getting breast cancer screening has gone up by nearly 40,000 in the last two years.
New figures show 344,000 women got free mammograms as part of the BreastScreen Aotearoa programme in the 24 months to October 2011.
Associate health minister Jo Goodhew says Maori and Pacific women had the biggest percentage increase with 8000 more getting screened.
She says that increase is encouraging because they are less likely to have breast screening.
A new TV campaign starts on Sunday 12 February to get more Maori and Pacific women to go for regular breast screens.
