"Known for his bareknuckle brawls in the back streets of Auckland, I have personally watched him take down many high-profile sports stars in arm wrestles while chatting up the local ladies and sipping away on a whisky, a huge testament to his arm strength."
At the weigh-in before his fight with Williams, Gurr turned the air blue with expletives and gave his opponent a shove in the chest.
"F ... you guys speak a whole bunch of crap. All I've heard from you is talk, talk, talk. Let's get it going," he said.
His aim was to knock out Williams in the first round, "so I can get to the bar".
Williams stopped Gurr 1 minute 22 seconds into the second round.
Gurr, who could not be reached for comment, will appear in court again next month.
