Malakai Fekitoa is hoping to inspire a generation of under-30 players to switch their allegiance back to smaller rugby nations.
And he says current All Blacks are backing him all the way, after he used an existing World Rugby loophole to pull on the Tongan jersey again this year.

The 29-year-old midfielder, who played 24 All Black tests up until 2017, has opened up to the Rugby Journal magazine about support he has received from fellow players.
"The guys in the current (All Black) team are supporting my decision," Fekitoa said. "They wish me well and they are all happy for me. A lot of them are islanders as well.
