The Waratahs are hoping to tap into the Crusaders' incredible Super Rugby record after signing former assistant coach Daryl Gibson for the 2013 season.
Gibson will work under new coach Michael Cheika and fellow assistant coach Alan Gaffney after four years as backs coach with the Crusaders.
The former New Zealand Test centre won four Super Rugby titles as a player and was part of the Crusaders set-up that made the 2011 final and qualified for the semi-finals in 2009, 2010 and 2012.
Cheika said Gibson's coaching knowledge would be crucial for the Waratahs next season.
"Darryl is the guy who most fitted the vision we have for the team and for NSW rugby," Cheika said in a statement.
"The new values that we are setting down he believes in already and that was the first thing we considered.
"To enact the change we want to make here, we need to change everything. I wanted someone fresh, someone that guys here haven't had much to do with or been coached by. We need to change the voices, change the approach.
"He has great experience of Super Rugby and in that sense his experience is a good complement for mine and Alan's.
NSW endured one of their worst ever Super Rugby seasons this year that ended with a record losing streak of eight successive defeats.
Gibson said he was looking forward to the challenge of turning that around.
"I was attracted to the role by Michael Cheika's vision for the team," he said.
"His passion and commitment to turning the Waratahs into a winning team made it an easy choice.
"The Waratahs underperformed last season and I know from Michael that the players are working very hard at the moment so they can earn the respect of fans and become a team that the people of NSW will be proud of and want to come and see."
Gibson will join the Waratahs next month.
