Mr Gordon faced a strong challenge from sitting councillor Paul Williams in campaign which at times was heated.
It saw a number of candidates using social media to challenge Mr Gordon and the council's debt levels, and to call for zero percent rate rises.
In a brief statement, Mr Gordon said he was relieved to win.
"Thank you to Waimakariri residents for re-electing me as your mayor," he said.
"It is humbling to be representing our district for a third term.
"I will continue to work hard for all of our communities, while listening carefully to your concerns and representing you to the very best of my ability."
Mr Gordon offered his congratulations to the successful council and community board candidates.

It has not been a good result for Mr Williams' team of six candidates, Standing Together For Waimakariri, with just Tim Bartle elected to the council, while James Bourke looks to have secured a seat on the Rangiora-Ashley Community Board.
Based on progress results, Mr Gordon will be joined by six sitting councillors - Niki Mealings and Tim Fulton (Oxford-Ohoka), Jason Goldsworthy and Joan Ward (Rangiora-Ashley), and Brent Cairns and Philip Redmond (Kaiapoi-Woodend).
It looks like there will be three new councillors Bruce McLaren (Rangiora-Ashley), and Shona Powell and Mr Bartle (Kaiapoi-Woodend), while former councillor Wendy Doody (Rangiora-Ashley) will return to council table.
Sitting councillors Mr Williams and Robbie Brine (Rangiora-Ashley) have lost their seats.
