The competition was held at Cowles Stadium in Aranui for the third year running on Sunday.
There were six games, including a juniors round and the final headline game featuring a battle between home and away teams.
Emma Derrick, who goes by the name Bella Spitfire when she's competing, has been part of the Dead End Derby league for more than 10 years.
"(It's) a really good sport, inclusive, empowering, a lot of stress gets relieved here," she said.
Roller derby teams include up to 15 skaters, with five from each team competing on the track at a time.
Derrick said some people get scared when they see the big hits but the players go through rigorous training beforehand.
"You don't go straight onto the big track, we have a programme that starts at the beginning of each term, learn to skate and learn to play roller derby, we teach you everything you need to know and to play safely."
Derrick said the gender-inclusive sport is social and everyone is welcoming and friendly.
As the sport grows, she hopes more people will be inspired to try it.
