The move also deepens the Highlanders’ ties to the Tasman Mako and the men from the Deep South will hope that Christie can introduce the defensive starch that has been evident in the Mako's play over the past two seasons.
“Obviously I am stoked to be able to work alongside Brownie, Derms and Flutes,” the 35-year-old said in a statement.
“The chance to coach defence for the Highlanders is an awesome opportunity and I can’t wait to get to Dunedin and get stuck into our work.
“It’s already been a big year and this is a great way to finish it for me”.
