All Blacks Ardie Savea and Jordie Barrett have re-committed to the Hurricanes and All Blacks through to the end of next year.
Loose forward Savea, whose brother Julian will leave to take up a contract in France this year, has played 25 tests for the national side, debuting in 2016.
"Wellington is my home town and it's great I can stay here and contribute as much as I can for the Hurricanes," he said.

"Also we know how important next year is for the All Blacks with the Rugby World Cup in Japan and I really want to be a part of that campaign."
Barrett, who has been used as a back-line utility, first appeared for the All Blacks against the Lions last year and has now played five tests, primarily at fullback.
"Hopefully I can play my part in helping the Hurricanes go as far as we can this season and next, and if my form warrants it, I can also be involved in the All Blacks."
Barrett said he had his own reasoning behind the relatively short nature of the deal.
"I've got a short-term focus. My next focus is trying to play well in Super Rugby and my aim is to go to the World Cup. Who knows what's going to happen after that.
"[A longer deal] was spoken about between my agent and I and we thought one year was best.
"Setting short-term goals and then just seeing what happens from there."
Their signings are good news for All Blacks coach Steve Hansen, as his team attempt an unprecedented three-peat of World Cup titles.
"It's great to have two young players recommitting to New Zealand Rugby and their Super club," said Hansen.
"Ardie and Jordie are both incredibly talented footballers in their own right, have been outstanding in our environment and done the jersey proud the jersey proud and we look forward to working with both of them."
Savea has been sidelined with an ankle injury since the All Blacks' third test against France last month, while Barrett is expected to take the field for the Hurricanes against the Chiefs in a Super Rugby quarter-final on Friday.
