A consistent performer for the Welsh region, Boshoff, 27, has made 34 appearances for the Ospreys and has been a regular name on the team sheet since officially joining from the Toyota Cheetahs on a permanent deal last season.
“This is a great club, and I’ve really enjoyed my time here up to now, so it was a no-brainer for me when it came to signing the deal,” said Boshoff on signing the deal.
“Even though I only officially joined on a permanent deal in the summer, my wife and I have spent a lot of time here with the loan spells and have been welcomed with open arms by the people in the region.
“I’m glad to be able to continue my career here and I’m looking forward to what the future holds as part of this group.”
Boshoff will compete with the regular pairing of Wales centre Owen Watkin and Kieran Williams for a place in the Ospreys midfield next season, but Phil Cokanasiga departs to Gloucester after agreeing terms with the English side.
“Evardi has become an important member of the squad, so we’re delighted that he’s signed a new deal with us,” said Ospreys head coach Mark Jones.
“He’s got that edge and calmness that you need in a centre at this level.
“His work rate is exceptional and he’s a smart, physical presence in the middle of the park on both sides of the ball. He embraces what the Ospreys is about and has been a consistent performer for us since he arrived at the club.”
News of Boshoff comes after fellow countryman Tom Botha also signed fresh terms yesterday.
