The Chiefs have re-signed talented scrum-half Brad Weber, loose forward Johan Bardoul and lock Michael Allardice.
All three players have committed for the next two years after featuring in this season's Super Rugby campaign.
Chiefs coach Dave Rennie is delighted that the trio have put pen to paper on their new deals.
“They're all good men with an excellent work ethic who have made big shifts in their game," he told the Chiefs' official website.
"We’re rapt these men have committed long term.”
Weber has been in electric form, with the 24-year-old drawing attention with his speed and skill.
"I am really happy at the Chiefs and didn’t want to leave," he said.
"We have consistency in coaching, which is important and I enjoy the family atmosphere. It is a very challenging environment but I believe that is really good for my rugby."
Both Bardoul and Allardice made their Super Rugby debuts this year and they have pleased the coaching staff.
At aged 27 Bardoul, who represents Bay of Plenty, was a late starter to Super Rugby but is rapt to get an extension after his first season at this level.
"I love the environment, the boys and the coaching," said Bardoul.
"I am learning lots and I want to win a Super Rugby Championship.
"It is also great to have my future for the next two years sorted."
Allardice has impressed both in his appearances for the Chiefs and in training, although he suffered a knee ligament injury last week that will keep him out of the rest of the Super Rugby season.
The 2.00m forward is enjoying his rugby and Allardice believes that is important.
"I have loved my time at the Chiefs and couldn’t see myself playing anywhere else," he explained.
"It was an easy decision for me to make, with the Chiefs great coaching staff, the playing environment and group behind the scenes."
