All Blacks winger Rieko Ioane has re-signed with New Zealand Rugby (NZR) for a four-year deal, recommitting to the All Blacks, the Blues and Auckland until 2022.

The 21-year-old is regarded as the world's best winger, scoring 18 tries in 18 tests for New Zealand, and was voted World Rugby's breakout player of 2017.

On top of securing Ioane on a long-term deal, NZR have also re-signed older brother Akira on a three year deal until 2021.

Akira, 23, has also recommitted with the Blues and Auckland.

"I feel incredibly privileged to get the opportunity to play my rugby here for another four years," said Rieko.

"I want to give it my best shot at serving the black jersey and, hopefully, I'll get the chance to play at the Rugby World Cup in the future. That's a huge motivator for me.

"It was obviously tough this year for the Blues, but I feel we're on the verge of something special and I want to be a part of that journey. Auckland is my home, it's where I grew up and it's the city that made me as a rugby player, so I want to do my bit to help it move forward."
