Sivivatu has scored 14 tries in his 12 Tests

The 25-year-old, born in Fiji, said he was keen to stay in New Zealand despite the flood of All Blacks players set to move abroad after the World Cup.

"There were some big offers from overseas," said Sivivatu.

"But I'm proud to wear the All Blacks' jersey and to be part of the New Zealand rugby family."

NZRU deputy chief executive Steve Tew added: "Sitiveni is a great talent and his decision demonstrates his commitment to New Zealand rugby.

"It also highlights the value of the black jersey."

Sivivatu has scored 14 tries in his 12 Tests.

All Blacks prop Carl Hayman was the latest high-profile All Black committed to leaving New Zealand after the World Cup.

The 27-year-old Otago prop signed for Premiership side Newcastle Falcons last month on a three-year deal after the World Cup.

All Blacks centre Aaron Mauger will join Leicester later this year, while scrum-half Byron Kelleher has agreed terms with French club Agen.

Chris Jack, Rico Gear, Luke McAlister and Anton Oliver are also poised for overseas moves following the World Cup.

The All Blacks have a strict policy of only selecting players who play in New Zealand.
