Dan Carter will put on the boots on New Zealand soil for the first time since 2015, after signing with the Blues for Super Rugby Aotearoa.
Carter's spent his last five years in France and Japan, but wants to give back to New Zealand Rugby.
He will be a player-mentor for the Blues, with Stephen Perofeta suffering a season-ending foot injury.
Carter's father Neville told Si and Phil he told Dan he had no worries with him playing up north.
"We're lacking rugby at the moment, so if you;re keen to give it a go then yeah go for it.
"It's an opportunity to give something back to rugby in New Zealand.
The Blues expressed interest in signing Dan in the past, and it was his Grandmother at the time who expressed distaste to him leaving red and black country.
But Neville said she has a different outlook this time around.
"She said she's finally decided, being at the age of 90, it's quite good that he's actually getting back into doing something with his rugby. So she was quite pleased overall."
Dan spent his entire 13 year professional career in New Zealand with Canterbury and the Crusaders.
Neville admitted he will back the Crusaders when they do meet the Blues, and hopes Dan does not get hit too hard.
