Dan Carter’s shock rugby comeback has everything to do with his love of the game and nothing to do with money.

The two-time All Blacks World Cup winner announced a Super Rugby comeback with Auckland Blues on Thursday at the age of 38, saying he realised during coronavirus lockdown how much he missed the game.

Carter, a three-time world player of the year, has been a free agent since returning to New Zealand in March from Japan, where a virus-enforced shutdown ended his lucrative stint with Kobe Steelers.

"Two things from the lockdown that I realised was that I really enjoyed spending more time with my family and that I miss rugby," Carter said.

"For me it is a chance to mentor some young players and to give back to New Zealand rugby," he added.

The signing comes as New Zealand's Super Rugby teams prepare to start a domestic tournament next week, after COVID-19 halted the southern hemisphere championship in March.

Carter has not played in his homeland since his international retirement in 2015, when he helped the All Blacks seal back-to-back World Cup titles at Twickenham.

Blues head coach Leon MacDonald said Carter signed a short-term deal as cover for injured fullback Stephen Perofeta.

He joins a squad already containing Beauden Barrett, his successor as All Blacks playmaker.

However, details have emerged of how little the All Blacks legend will earn, in order to fulfil a dream Super Rugby return.

As a replacement player, Carter will reportedly be on a minimum contract worth NZ$1,800 ($A1,674) a week, a huge cut from the millions he earned playing club rugby in France and Japan.

"It definitely not about money, he's not getting rich doing it," MacDonald said.

As the Blues already have Barrett - himself a two-time world player of the year - Carter may fill the role of super-sub off the bench.

"I have not played for several months so it will take me a little bit of time to get game-ready," he said.

Former All Blacks coach Graham Henry had no doubt Carter still had the ability to play at the top level, despite his age.

"It's marvellous, he'll add a huge amount of experience but he's also been playing very well in Japan," Henry told Radio New Zealand.

All Blacks halfback and former teammate Aaron Smith tweeted: "The goat (greatest of all time) is back in Super rugby!"

MacDonald indicated Carter would be behind Barrett and rising star Otare Black in the pecking order.

"If he gets back into playing form that warrants selection, then he could help us as a utility back in midfield or fullback," he said.

Carter played the first of his 112 Tests for the All Blacks in 2003, scored a record 1,598 points during his international career and was the world player of the year in 2005, 2012 and 2015.

He played for French club Racing 92 after retiring from Test rugby following the 2015 World Cup, before signing a two-year deal with Kobe Steelers in 2018.

The South Island native already has three Super Rugby titles from his 13-year stint with the Canterbury Crusaders and remains the competition's top points-scorer with 1,708.

Often described as the best fly-half to play the game, Carter revealed in his autobiography that he turned down an approach from the Blues in 2009 after his Crusaders-supporting grandmother Pam Carter opposed the move.

However, Nanna Carter said on Thursday that she had no problems with the latest deal and would support the Blues over the Crusaders when her grandson was playing for the Aucklanders.
