New Zealand assistant coach Ian Foster and forwards coach Mike Cron have extended their contracts until 2017.
Since Foster's arrival as an assistant in 2012, the All Blacks have claimed 49 wins, two draws and lost just three times in 54 Tests.
And, after New Zealand successfully retained the Rugby World Cup by beating Australia in last month's final, he and Cron have been rewarded with extensions.
"It's great news for New Zealand Rugby and myself to have these two world-leading coaches sign back on with the All Blacks," New Zealand coach Steve Hansen said.
"They have both played a major part in making this team what it is.
"They understand the culture and what's required in the Test arena to make a team successful, and will be vital in making sure that we continue to grow our game in the years ahead."
