The Raiders have locked down winger Michael Oldfield on a two-year deal.

Oldfield will remain at the green machine until the end of 2020 as the Raiders continue to solidfy their squad for the future.

The new deal comes just after Oldfield starred in the Raiders' huge 38-12 win over the North Queensland Cowboys in round 18, scoring a hat-trick of tries.

Oldfield has told he is thrilled to have resigned with the club and will continue to push for more NRL game time.

"I'm really enjoying my time here in Canberra and to sign a new two-year deal is great for my career," Oldfield said.

"It's great that Ricky and the coaching staff have given me the opportunity to get into the NRL team over the past few weeks and I'm really enjoying my footy at the moment,."

Having played just five games for Canberra in 2018, Oldfield has scored four tries and has made a total of 645 running metres.

Raiders Recruitment and High-Performance Director Peter Mulholland said the experience and professionalism Oldfield displays at the club makes him a wonderful player to resign.

"Michael is an experienced player who showed against the Cowboys just what he is capable of when given the opportunity to come into the NRL team," Mulholland said.

"He's also very professional in his approach to his training and is a great role model for younger players in the squad.

"We believe Michael will continue to be a very valuable member of our squad over the next two seasons."
