Police say Mr Scullin was assaulted with a wooden fence paling while trying to break up a fight outside his house the night before, but did not die as a direct result of the assault.
Two other Tauranga men, Zodiac Wiremu Taikato, 20, and Shem Williams, 21, who also appeared in court today, denied a joint charge of participating in an organised criminal group.
The two men, who have also elected to defend the charge at a jury trial, and Anthony Taikato were further remanded on bail.
He is also due back in court on March 10 for a case review hearing.
Another man Lance Perawiti, 19, also charged with participating in an organised criminal group was further remanded on bail to appear back in court on January 14.
He is expected to enter a plea to the charge on that date.
