Gibbes said he is delighted to be able to continue with the Waikato Rugby Union.
"I have thoroughly enjoyed my first four seasons as coach of Waikato. It is my home province so naturally I have a lot of passion for the job, but also it has been a pleasure to work within such a well-respected organisation."
He says he is also looking forward to carrying on his work with the young talent coming through the Waikato system, as well as assisting club coaches during the club season.
"2012 was a rebuilding season of sorts after losing a lot of experience. Our young group of players, many having their first taste of rugby at this level, showed some positive signs and I am excited to be able to work with them again as we reap the benefits of the experience they gained in this year's ITM Cup."
