Rotorua's roller derby club, the Sulphur City Steam Rollers, are ready to rock with their annual fundraising event, Slam Rock 2017.
Slam Rock, now in its fourth year, is a sporting event unlike any other in New Zealand.
Along with mirror balls, spotlights, great music, fun, and frivolity, not to mention the annual Slam Rock Air Guitar Competition at half time, comes an action packed game of roller derby.
This year Hamilton's "Hellmilton Roller Ghouls" are sending their travel team "Raggedy Angst" to take on Rotorua's "Motley Crew" in the hard-hitting full contact game played on roller skates at the Southern Trust Sportsdrome.
It will be the third time the teams have played each other, and with one win each, Slam Rock will see Raggedy Angst and Motley Crew battle it out for the best of three.
Sulphur City Steam Rollers chairwoman, Layla Robinson, a.k.a Primevil, said Motley Crew had taken the win at all three previous Slam Rock events so the pressure was on as it always was on home turf.
"But we go into all our games with a great attitude and have often been told we're one of the most fun teams in New Zealand to play, so I think we have a good balance of being competitive and being great sportspeople."
In the game of roller derby, which is full contact and has been likened to "rugby on skates", players skate around an oval track in a pack made up of eight players, four from each team, who hold the position of blockers.
Blockers must remain within a certain distance from each other at all times.
