The Blues have appointed North Harbour coach Steve Jackson as their new assistant-coach for the 2017 Super Rugby season.
Jackson will be in charge of the forwards with Glenn Moore's contract having expired. Nick White's position as scrum coach has also been scrapped.
Jackson has worked with Blues coach Tana Umaga before when they were both at Counties Manukau.
"I had to go through a process, like everyone else, and I was just thankful that I was successful," Jackson said of new job.
"I'm looking forward to getting that relationship going again with Tana, because I know what he brings as a coach. I've had a bit to do with (fellow Blues assistant and defence coach) Alastair Rogers too and I like what he brings to the table."
Meanwhile the Western Force have added former Australia and Ireland assistant-coach Alan Gaffney to their coaching staff.
Gaffney, who served as the Australian Rugby Union's elite programmes coach, will be an attack specialist.
“I suppose an old bugger like me has been around the traps, that’s not to say I’m always right, but it means as a coaching group we will be able to challenge each other,” Gaffney said.
“I think adopting a different attitude to the way they play from the last couple of years is going to be pretty exciting for the Force. There are a number of good young players that are really hungry to play and don’t play with fear, so it’s an exciting time."
