Former NRL player Craig Field has been found not guilty of murder but guilty of the manslaughter of farmer Kelvin Kane outside a north coast pub.

Mr Kane, 50, was found lying unconscious outside the Kingscliff Beach hotel on the NSW north coast on July 15, 2012. The Tweed cattle farmer was placed on life support in hospital but later died.

Craig Field said he had tried to act as a "peacemaker" in a fatal dispute.

On Tuesday a NSW Supreme Court jury sitting in Lismore delivered their verdict following a three-week trial.

The former South Sydney rugby league captain had been on bail during the trial but it was revoked by Justice Elizabeth Fullerton after the verdict was handed down.
