Rotorua's roller derby league are hosting a team from the South Island for the first time at this weekend's sixth annual Slam Rock event.
It is the first time the Sulphur City Steam Rollers have played Christchurch's 'Living Dead Rollers' on home-ground, and the first time a team from the south has been invited to the coveted annual event.
Often described as similar to 'rugby on skates', roller derby is a fast-paced game that relies heavily on strategy, strength and speed.
Each team fields a 'jammer', one skater whose goal is to score points from each opposition skater they pass.
The other skaters on the track are 'blockers' who are trying to stop the opposing jammer, as well as giving assistance to their own.
