People are notified if further investigation is required, which is typically done through a colonoscopy. Like the test, follow-up investigation and treatment is free.
Bowel cancer is treatable if picked up early. People diagnosed with early-stage bowel cancer who receive treatment early have a 90 per cent chance of long-term survival.
Whanganui was the ninth DHB in the country to launch a DIY bowel screening programme in 2019, and has seen significant uptake across the wider region.
Bowel screening co-ordinator Judy McIntyre said even under lockdown conditions, the screening programme was going well.
"We continue to have good participation rates for our region and we are still diagnosing cancers through the programme.
"So we encourage anyone who has received a kit but hasn't yet completed it, to do so."
Whanganui GP John McMenamin, the Ministry of Health's bowel screening lead for primary care, said screening was fundamental in picking it up early.
"There may be no warning that you have bowel cancer, so doing the bowel screening test is an easy way to identify that something might be wrong.
"I encourage all patients in the 60-74 year age group to complete their kit when it arrives in the mail."
