Wright's wife is an Aucklander and he himself had played for Auckland in the 2013-14 and 2014-15 Super Smash tournaments, scoring 188 runs in ten innings and taking two wickets.
"I really enjoyed my time on the pitch with the team but it was the memories of how my family and I were treated that stood out," Wright said.
"My core values as a coach are to build relationships and belief in players. When players have confidence and belief, amazing things can happen. I can't wait."
Auckland head coach Doug Watson is looking forward to working with Wright.
"He will bring fresh ideas to our set-up and has a good understanding of our team culture," Watson said. "Having someone of the calibre of Luke in our setup will be great for the development of the players and our overall team environment."
On the coaching front, Wright has had stints with Melbourne Stars (BBL), Rajshahi Kings (BPL) and Southern Vipers women (Rachael Heyhoe Flint Trophy).
