"There really is a lot of momentum and many positive things happening across the district at the moment."

"We have robust discussions, make decisions and move forward without the posturing and politics you see in so many other councils.
"I'd like to thank our elected members, iwi representatives and staff for all the hard work they do on behalf of their community, in particular my deputy mayor, Phil Nixon, who has been a terrific support."
