The Sulphur City Steam Rollers' Motley Crew aim to spook Aucklanders, the Broadside Brawlers in a wicked night at the Hell-O-Wheels roller derby.
Steam Rollers chairwoman Layla Robinson is inviting the audience to take part in tomorrow night's spooktacular and dress up Halloween style.
"It's going to be hard to beat the audience from Slam Rock when about 40 per cent of people were dressed up. It was outrageous. But I'm laying down the challenge to beat it. It's going to be a lot of fun," she said.
Prizes will be given to the best dressed adult and child Halloween costumes, as well as those with the best supporter signs for their favourite team or skaters.
Half-time entertainment will include a performance by young members of the Rotorua Roller Skating Club, and kids in the crowd in costume will be invited down to the track for treats.
