The Waikato Rugby Union has released head coach Tony Hanks to take up a position as the director of rugby at the London Premiership side Wasps.
The appointment comes a day after the British and Irish Lions coach Ian McGeechan stepped down from the role.
Chris Gibbes takes over as head coach of Waikato for this year's Air New Zealand Cup.
Gibbes, who is 36, was Waikato's assistant coach last season.
Scott McLeod, who is currently the skills coach with the Chiefs and last year was skills coach with the Waikato team, has been appointed as the assistant coach to the Waikato team.
Hanks initially linked up with Wasps in 2002, leaving in 2005 when he returned to New Zealand, and was latterly Waikato's head coach.
He also spent time with Wasps this season, working on secondment between November and April to support the coaching staff of McGeechan, Shaun Edwards and Leon Holden.
