Taranaki loose forwards Lachlan Boshier and Mitchell Brown have extended their contracts with the Chiefs for another two years.
The Super Rugby side, who will be coached next year by Taranaki's Colin Cooper, announced on Tuesday that the pair had signed on until the end of the 2019 season.
Boshier, 22, was first called in to the Chiefs last season as injury cover, making his debut in their match against the Waratahs and was offered a one-year contract this season off the back of a good Mitre 10 Cup season with Taranaki.
It was a similar story for Brown, 23, who really impressed when the Chiefs thumped Wales in Hamilton last season. He too was offered a contract this season after some noteworthy performances in the provincial competition.
The pair have also signed on with Taranaki for the same period.
"It's bloody good to have some security and know where you are at compared to previous years when everything has been up in the air a little bit," Brown said.
Just being able to plan what was in front of them for that period "was a real treat" Brown added.
Boshier said their contract extensions followed discussions with Chiefs assistant coach Andrew Strawbridge who was keen for the pair to stay on as two of the younger members of the squad.
The Chiefs are losing a number of established players next year with the likes of co-captain Aaron Cruden and James Lowe amongst a group to have taken up overseas contracts.
Brown and Boshier said they had fitted seamlessly into the Chiefs environment in their first full year.
"It's been made a lot easier by being here last year for that short bit, so I knew a lot of the boys," Boshier said.
They have been reasonably happy with their form although Brown was bitterly disappointed to only last three minutes of the Chiefs match against the Cheetahs in Bloemfontein when he left the field with concussion.
Fortunately he had suffered no further symptoms and would be available for selection in required against the Reds in New Plymouth on Saturday night.
