"I wear a number of different hats as a farmer, a business owner and I am also a keen environmentalist. The situation we're in now with our waterways has happened over many decades and I knew that even though it would take up nearly all of my time, it was something I had to do".
He recalled being presented with a stack of bulging folders to read over the summer before starting with the zone committee and feeling a bit overwhelmed at the first few meetings.

"It's a real credit to the committee that although we're from different backgrounds and have a wide range of views we've come up with recommendations that will improve our waterways. It won't happen right away, but it is a step in the right direction.
"We devoted so many hours and put the rest of our lives on hold to do something that we hope will benefit the wider community.
"To be honest, it's going to be really hard on farmers and I hope that the broader public will support us as we work together to clean up our streams and rivers".
Ashby will remain on the committee as a community member, while Michael Blackwell takes up the role of chair, with Cam Henderson as deputy chair.
He said it's an exciting time for the committee as they work on catchment management plans and take visible action to improve Waimakariri's waterways.
"We're looking forward to working together with the wider community on local projects to enhance biodiversity, streams and rivers. The most important thing is that we all recognise the problem and take joint action to fix it".
