Earlier this month Morrison - now 45 years old and a mother of three - was urging Kiwi women, especially Māori, to enrol for free breast screening this October after having her first mammogram.
"It's a bit scary, but I promise you it's scarier not to do it," she said.
BreastScreen Aotearoa, the national screening programme, offers free two-yearly mammograms to eligible women aged 45-69.
Nine women a day are diagnosed with breast cancer in New Zealand - that's 3000 a year.
Funds raised from the event will go towards researching new breast cancer treatments, promoting awareness and educating to save lives as well as supporting those battling the disease.
A Pink Star Walk will take place in Wellington next Saturday, November 3, and in Christchurch the following Saturday, November 10.
The facts:
• More than 600 New Zealanders died of breast cancer every year.
• Māori have a 65 per cent higher breast cancer mortality rate than non-Māori, but when their cancer is found on a mammogram, their survival rate is the same as non- Māori.
• A breast cancer patient has a 92 per cent chance of surviving for 10 years if her cancer is detected by a regular screening mammogram. That figure drops to 75 per cent if a lump is the first sign.
