Christchurch Surgeon and Bowel Cancer NZ medical adviser Frank Frizelle has cautioned against over-interpreting studies that seek to prove a link between nitrates and bowel cancer.
A medical adviser for Bowel Cancer NZ has criticised studies linking lower levels of nitrates in drinking water with an increased risk of bowel cancer. A major Danish study published in 2018 found a significant increase in bowel cancer when nitrate levels were just 0.87 milligrams per litre of water and a 15 per cent increase at 2.1mg per litre. The current safe level in New Zealand, as mandated by the World Health Organisation (WHO), is 11mg per litre.

Michael Hooky Walker was left with 50 fractures after crashing his motorbike. After a month in coma, he is now on the slow road to recovery at his home in Lake Coleridge.
A quick motorbike ride before a family dinner could have been Michael “Hooky” Walker’s last. It was supposed to be a 20-minute journey on his cherished Harley-Davidson. But the 47-year-old’s next memory after the October 24 crash was waking up from a month-long coma with more than 50 fractures scattered throughout his body. Walker was about 6km from his Lake Coleridge Village home in rural mid-Canterbury when he took evasive action to avoid lambs partially blocking the road.
