Exeter

The 27-year-old joins from Super Rugby franchise, Moana Pasifika, where he spent the 2022 season.

The back began his career in rugby league, playing for New Zealand Warriors and Melbourne Storm, before switching to union in 2020.

Kata spent two years playing with the Brumbies in Australia and has been capped by Tonga in both codes.

He made his Tonga debut in the autumn international tdefeat by England at Twickenham in November.

"I've watched a few games and I know it's really physical here in the UK," Kata said.

A statement from the Somerset club said Premiership Rugby would determine the points allocation for the cancelled game over the coming days, while their league clash with London Irish on January 3 is unaffected.

“It is with regret we share that our Round 3 Premiership Rugby Cup fixture against Exeter Chiefs scheduled for Wednesday 29 December at the Rec cannot go ahead safely,” read a statement on bathrugby.com.

Two Owen Farrell penalties gave Sarries an early lead but Luke Cowan-Dickie's try and a Gareth Steenson penalty saw the home side go into the break ahead.

A Farrell penalty hit the post at the start of an error-strewn second half.

But scores from Harry Williams and Matt Kvesic, plus a penalty try, sealed the victory, with Ben Spencer's effort a mere consolation for Saracens.

The win moves Exeter three points above Saracens at the top of the table as they approach the midway point of the season.
