Titans forward Leivaha Pulu has signed with the Warriors on a three-year deal, while James Gavet has re-signed with the NRL club for an additional two years.
The Warriors' first-choice prop duo for 2018 appears all but settled after Leivaha Pulu and James Gavet both confirmed their presence in Auckland from next year.
Titans forward Pulu, 27, has signed for the NRL club on a three-year deal after a breakout season on the Gold Coast, while Gavet has re-signed through to 2019.
The hard-running Pulu, who weighs 115kg, was born and raised in New Zealand before moving to the Gold Coast as a teenager and bloomed late at the top level.
He has made 34 Titans appearances, having spent a journeyed early career at the Wests Tigers, Wyong Roos and French club Lezignan Sangliers.
Pulu also made his international debut for Tonga earlier this month.
Gavet has also found his feet in the NRL after a number of injuries and personal issues.
"They both bring size and plenty of enthusiasm and aggression in the way they play the game," Warriors recruitment manager Tony Iro said.
"James was in our NYC and NRL squads in 2009 and 2010, and always had potential - it has taken him time to get to this level, but he's had a really impressive season.
"We've been interested in Leivaha for a while - he has worked hard for his opportunity in the NRL and has made a real impact."
Of the Warriors' other front rowers, Jacob Lillyman, Charlie Gubb and Albert Vete are all off-contract at the end of 2017, while stalwart Ben Matulino has already signed for Wests Tigers.
Sam Lisone's contract expires at the end of 2018, and Ligi Sao a year later.
