A quartet of key Hurricanes including new All Blacks Ngani Laumape and Vaea Fifita have re-signed with the Hurricanes for 2018 and beyond.
Laumape and Fifita have joined midfielder Matt Proctor and lock Geoff Cridge in signing new deals.
Laumape, who made his test debut against the British and Irish Lions series will remain with the Hurricanes and Manawatu for at least two more seasons.
"Coming back to rugby union from rugby league in 2016 was a massive challenge, but the Hurricanes coaches have made the transition a lot easier and I've loved every minute," Laumape said.
Fifita, made his All Blacks debut off the bench against Samoa in Albany last month, and has signed through until the end of the 2020 season.
"Representing the All Blacks was a dream come true....I know I still have a long way to go and the Hurricanes is the right place for me to continue my career."
Proctor, who has played 43 matches for the Hurricanes since his debut in 2013, has re-signed for two more years.
Cridge, a 22-year-old, two metre tall lock out of Hawke's Bay, said he was grateful to the Hurricanes coaching staff for showing faith in him after an injury interrupted 2017 has seen him unable to add to his single Super Rugby appearance.
"It's been tough not being able to contribute on the field, but I I've learnt a lot from being in the Hurricanes environment and I can't wait to make an impact in 2018."
Hurricanes coach Chris Boyd said he was looking forward to watching all four players continue to develop in coming seasons.
"We are very lucky to have some great talent at the club right now in a lot of different positions and to be able to lock in players of the calibre of Ngani, Vaea, Matt and Geoff for next year and beyond is great.
"All of these guys are in their early to mid-20s and that allows us to move forward with some real confidence."
