Nah.
That is a load of crap. They went looking for trouble.
These facts were not disputed in court by the defense, only that it wasn't Fainu who stabbed him and was mistaken identity.

Manase Fainu found guilty of church stabbing
Earlier in the night, a group of Fainu’s friends had been told to exit the premises. Yet CCTV footage captured them jumping over a nearby wall to get back into the church car park.
“Manase Fainu jumped over a fence into the grounds of the church,” Crown prosecutor Emma Curran laid out during the trial.
“He was with four of his friends and the group of them approached Mr Levi and his friends.
“A brawl broke out and when things looked like they were getting out of hand, Mr Fainu pulled out a knife and plunged it into the back of Mr Levi.”
