"Working with people who hold a range of differing views and trying to come to a consensus on how we could make a positive difference to the environment was a learning curve, but through listening to each other we were able to achieve a lot in a short amount of time and come up with a plan that reflected what the community told us they wanted to see."
The passion of committee members and the community for leaving Waimakariri's waterways in a better state than they found them was evident throughout his time on the committee, Ashby said.
Getting farmers on board and having rūnanga representatives as committee members was also vital for developing a full understanding of the local environment.
"We learned the cultural values of water, and these were applied to everything that we did around the committee table and in the community. Getting the rural community engaged and involved in the process was really important too."
Oxford farmer and DairyNZ associate director Cam Henderson, joined the committee in 2017 - part-way through the PC7 process.
He said the support the committee received from Environment Canterbury's science team was invaluable.
"They explained the technical data to us in a way that both the committee and community could understand and this was a very important part of the consultation process."
Henderson also learned a lot by listening to and interacting with committee members and residents who held alternative views to his own.
"For me it was a real learning experience, and I even changed my original views on some points over time. That's the benefit of the collaborative approach and having the time to question things and to get to the heart of issues."
Being able to front up to public meetings and speak in front of hundreds of people was another new experience for Henderson.
"We had to speak in front of our peers and emotions were running high, so you had to learn how to adapt and deal with difficult situations.
"Going out to the community and really listening and engaging with them takes time and I am really proud of what we were able to achieve as a committee."
Both Ashby and Henderson hoped the thousands of hours collectively contributed to the Zone Implementation Programme and Addendum (ZIP and ZIPA) by the Waimakariri Water Zone Committee, Waimakariri District Council, Environment Canterbury, local iwi, and the wider community will be reflected in the PC7 document which is due to be considered by Environment Canterbury's Council later this year.
"We mapped out a pathway to a better future for waterways throughout Waimakariri and retaining a local approach where our community takes action to tackle district-wide environmental issues is the key to improving our rivers and streams," Ashby said.
