The New Zealand Rugby Union have guaranteed that Blues coach Pat Lam will stay in his job throughout this Super Rugby season despite a disappointing 1-5 start.

However New Zealand Rugby Union chief executive Steve Tew said Lam will get help in his role as coach from World cup winning coach Graham Henry who is contracted to the NZRU work with the NZ Super Rugby franchises

Henry will surely be keen to help the Blues as he coached them to their first two titles in 1996 and 1997 and was technical advisor when they won their third and last title in 2003.

"We've got Sir Graham contracted and Sir Graham has a programme of work that includes spending time with the Blues and he's doing that but he's also spending time at the Hurricanes who we were having similar conversations about this time last year," Tew said.

"There's always going to be a team under pressure because they (the Blues) are coming last in the New Zealand conference. "

"This year it's the Blues, last year it wasn't," Tew told Stuff.

"So we will use Sir Graham, but we're not going to put Sir Graham in fulltime to coach the Blues, that's not something that the Blues want or that we think would be appropriate right now."

Under-fire Lam broke down at a press conference on Wednesday when he told reporters of racial comments posted by the team's critics on social networking sites.

The former All Blacks and Samoa rugby international described as "deeply offensive" comments - some of which were posted on the Blues' own website- which drew attention to the Pacific Island and Maori heritage of the coach and many players.

NZRU chief executive Steve Tew said Thursday the New Zealand Rugby Union has "zero tolerance for any racial abuse or activity."

"As a New Zealander, because I don't think this is only a rugby issue, I'm appalled," Tew said.

"I find the whole ability by people to hide behind social media and be faceless and to criticize people personally and to bring race and religion or anything else into it, is just a very disappointing part of our country."

Lam has an option to extend his Blues contract by a year after this season and Tew said his position would not be reviewed before the end of the current season.

"This is a private employment matter so I can't really say much more than that," he said.

"I imagine Pat is only wanting to focus on what is ahead of him today and tomorrow and Saturday."

In New Zealand, all Super 15 Rugby coaches and players are centrally contracted to the New Zealand Rugby Union.

Individual teams can select players and appoint coaches but they are contracted and paid by the national union.

The Blues will have input on Lam's future but the final decision on his reappointment after this season rests with the NZRU.
