A New Plymouth jury has found Robert Douglas Clement, 47, guilty of a brutal assault in Eltham more than two years ago.
After 2 1/2 hours deliberation this afternoon, the jury returned a unanimous verdict finding Clement wounded Michael John Hardgrave with intent, causing him grievous bodily harm after attacking him outside the Central Tavern on Easter Monday 2010.
A second man, Noel Lee Bland, received a six-year prison sentence after he was found guilty of the same offence at a trial in June last year.
Police say after evidence heard at trial, they will now look into the involvement of a third man, former All Black Bryce Robins.
Robins was the proprietor of the pub at the time but is now believed to live in Australia.
