The heavy metal music seemed tame under the sounds of clashing weapons and armour, and shouts from the crowd.
"Put him down! Get an axe in there! Hit him!"
This was the Sulphur City Clash Full Medieval Armed Combat Tournament. Teams travelled from as far as Auckland and Wellington to take part in a literal fight to be the last man or woman standing.
The sport requires team members to wear up to 40kg of armour and fight with metal weapons in a ring.
There are rules controlling the specifications of weaponry and armour, where opponents can strike each other and how many times they can balance themselves, but that doesn't stop competitors from taking big hits.
"It is brutal," Liz Dufty told the Rotorua Daily Post.
Her husband Chris has been part of the Ohura team, the Steel Thorns, for two years.
Dufty has become a strapper.
"I strap them in the armour. There is a lot to tie up, a lot of buckles too, and weapons to provide where needed."
Team member Justin Stockbridge is a full-time armourer and teaches others to make their own.
His business All Fired Up Armouries sponsors the team.
"It is expensive, about $5000 a set," Dufty said.
She said there were about six tournaments a year in New Zealand, and "people do get hurt".
"The steel armour is designed to be bent not broken, so the wearers do get bruising. People don't normally break bones unless they have fallen wrong. "
Despite this, Dufty said she was not worried when her husband joined the team.
"He can handle himself."
And it is not just men that fight.
Dayna Berghan-Whyman was part of a Wellington team named Felag.
"As you can see, we need so much help when we are on the field and when we are in armour," she said after she was helped taking off her helmet.
She then guzzled back some water in a 10 minute rest between rounds.
"We were going to be back-to-back, that is why they have given us a bit of a break, but we do not get fully unarmoured."
Erika Jack was just going for walk in the park with her family when they came across the tournament.
"At first I thought it was part of the Kuirau Markets," she said.
"I love the costumes! I have never seen anything like this in my life. I did not think New Zealand did this."
Organiser and Rotorua fighter Nicholas Matepo Waiariki said he was "really happy" with the turnout at the Medical Officers Reserve beside Mataatua Marae.
"The weather is good. We have some good trophies up for grabs, and we have six teams."
The tournament was held from 10am to 4pm on Saturday and Sunday.
