Aaron Smith commits to New Zealand at least until 2021

All Blacks scrum-half Aaron Smith has pledged his immediate future with New Zealand Rugby after signing a new two-year deal.

The news will be a big boost for New Zealand Rugby with the likes of Ben Smith, Kieran Read and Owen Franks will head overseas post the upcoming World Cup in Japan while Nehe Milner-Skudder has already signed a deal with Toulon.

Meanwhile, Ryan Crotty, who has played 44 Tests for the All Blacks will join Japanese club Kubota Spears following the showpiece event later this year.

"I know I'll look back at the end of my career in New Zealand with really fond memories of the experiences I've had and what I've achieved alongside my good mates," said Crotty.

"For now my focus is enjoying the season ahead and helping to lead this Crusaders side one last time in 2019."

Meanwhile, Smith has played 82 Tests for New Zealand since his debut in 2012 and was recently part of the European tour last year. The 30-year-old scrum-half has also been part of Highlanders since 2011 racking up over 100 appearances for the Super Rugby club.

"We're delighted to have re-signed Aaron through to 2021," said New Zealand Rugby chief executive Steve Tew.

"He's a proven world-class player, the most capped All Blacks halfback ever and an incredibly important member of the All Blacks and Highlanders."
