1:15 Nitrate in our water linked to bowel cancer

New Zealand has one of the highest rates of bowel cancer in the world and a recent study has found there's a link between nitrate in water and the risk of developing this cancer. 

In some areas around the country, nitrate levels in the water are higher than what is recommended in the study. 
So the obvious question is, could drinking it be contributing to our high bowel cancer numbers? 

That's what Victoria University's Mike Joy and Otago University's Michael Baker have been looking into. Professor of Public Health Michael Baker explains what the concerns are.

The Sevens were this weekend - the second year it's been hosted in Hamilton - and by all accounts it was a success.

At the end of the day though it's less about the games and more about the experience, something organisers discovered in Wellington. So will we see a repeat? We're joined by Hamilton Mayor Andrew King.
