The Crusaders will beef up their coaching team in 2013, bringing the total to four, after a review of this year's season identified some shortcomings with the existing setup.
Todd Blackadder (head coach) and Dave Hewett (assistant forwards coach) will retain their roles but Daryl Gibson will take on defensive responsibilities. The trio will also be joined by an attack coach, with the job being advertised this week.
"At the end of any season we conduct a thorough review of what worked, what didn't work, and what we will do differently next time," Crusaders chief executive Hamish Riach said.
"While we are very proud of the team for making the playoffs once again this year, we all want to do even better than that next year. So we've been taking a long, hard look at where our performance this season could have been improved and approached all possible changes with an open mind.
"This is one of the changes that the coaches, management and board all believe will put us in the best possible position to maximise our performance in 2013."
