Pollock first joined Saints’ academy at Under-13s level, and by the time he was 17 he had already featured for the senior side in the Premiership Rugby Cup.
He has played nine games for Northampton this season and scored a try against Castres in his European debut for the club earlier in December.
Pollock says his emergence at Northampton, having come through the club’s junior ranks, has “been a really special experience”.
“I’m very grateful to be able to sign on again here at my boyhood club, I’m loving how things are going at the minute,” he said.
