Bowel screening age lowered to 58 for thousands of New Zealanders

Wednesday, 25 March 2026

Health Minister Simeon Brown says the move will give 40,000 more people access to 'lifesaving' early detection.

Thousands more New Zealanders are now eligible for earlier bowel cancer screening as the starting age drops from 60 to 58 across most of the country.

The age change is now in effect across the North and South Islands, with MidCentral scheduled as the next district to join the rollout. Health Minister Simeon Brown said approximately 40,000 additional people will become eligible in the first year, with most newly eligible 58 and 59-year-olds expected to receive invitations for free screening by April 2027.

While welcomed as a first step, health experts argue the change still misses the fastest growing group of patients, those under 50.

The expansion aims to prevent an estimated 771 bowel cancers and 566 deaths over 25 years. Brown said the staged rollout ensures the workforce and endoscopy services have the capacity to support increased demand.

A separate 'FIT for Symptomatic' pathway is also being implemented nationwide to assist people of any age experiencing symptoms. This pathway allows clinicians to use a stool sample test to triage patients, which is expected to reduce non-urgent colonoscopy referrals by at least 30 per cent.

The symptomatic testing is currently available in Auckland, Counties Manukau, Waitematā, Waikato, and Hawke’s Bay. The remainder of the country, including MidCentral on April 20, is expected to have the pathway in place by the end of September.

Brown said the changes are intended to align New Zealand’s screening age with Australia and improve early cancer detection.
