KEY POINTS:
The Dead Wreckoning and Mascara Massacre teams battled it out in the quarter finals of the roller derby competition in Auckland last weekend.
The two teams locked wheels in the US-inspired, all-girl contact sport at Skateland, in Mt Wellington, on Sunday.
Gathering momentum in the US, the sport is catching on fast in NZ as well after being introduced in February.
There are 10 players on a rink at a time, five from each team.
Each team involves a jammer and four blockers. The jammer scores the points and does this by passing the opposition. The blockers have to stop the other team's jammer and help theirs through by pushing the other blockers, either with their shoulder or hip.
There are three periods of 20 minutes and in each round there are two-minute countdown periods called a "jam", when the teams try to score points.
Herald photographer Kenny Rodger was at Sunday's match to capture Dead Wreckoning's convincing win.
