Hawke's Bay has become the seventh region to take part in the National Bowel Screening Programme aimed at detecting early signs of bowel cancer.
HBDHB Clinical Lead of Gastroenterology, Dr Malcolm Arnold, said taking part in the programme could be life-saving, thanks to early detection.
One in 18 males and one in 21 females will experience bowel cancer by the age of 75 in New Zealand.
"The National Bowel Screening Programme will identify cancers earlier and allow us to remove precancerous polyps which will in the medium to long term reduce the incidence of bowel cancer," Arnold said.
All eligible Hawke's Bay residents, aged between 60 and 74, were automatically enrolled in the programme and pre-invitation letters would be sent out daily, starting this week, via a birth date system, taking approximately two years to reach all residents.
