All Blacks prop

The 13-Test prop will remain with the Highlanders and Southland.

"It was an easy decision to stay in New Zealand," said de Groot.

"All I want to do is play for my country and represent my home region."

RNZ reports after missing selection for the series defeat to Ireland, de Groot fought his way back into the squad and cemented himself as the first-choice loosehead for the remaining 10 Tests of the season.

"We are proud of the work Ethan has put into his career so far," said NZR chief executive Mark Robinson.

Moody missed the All Blacks last two games against Australia as he went through concussion protocols, while Laulala did not initially travel with the team because he was on paternity leave.

"Joe has come on nicely, and is certainly going to be available this week," All Blacks assistant coach John Plumtree told reporters on Tuesday. "He was really close last week and we chose to keep him out for his safety. But he is good to go now."

The news is a boost for the Blues who have lost first five Bryn Gatland to the Highlanders from next Super Rugby season.

Tuungafasi joins utility back Damian McKenzie, halfback TJ Perenara, flanker Sam Cane and hooker Codie Taylor as All Blacks who will stick around at least two years beyond next year's World Cup in Japan.

Tuungafasi, who has played 14 times for the All Blacks and 63 times for the Blues, has also re-signed with his Auckland Mitre 10 Cup province.

The 30 year old has played 46 times for the All Blacks, including the 2015 World Cup final, and has represented the Blues in Super Rugby since 2009.

RNZ reports he will still compete in next year's Super Rugby competition before heading to the northern hemisphere in time for the French season according to Sky Sports UK.

Faumuina said it was a difficult decision to leave New Zealand but he was excited by the opportunity in Europe.
