Like the ice-based version, inline hockey is all about co-ordination, speed and skill.
But while both sports use sticks and pucks, wear masses of protective clothing and have team names like Blackhawks, Penguins and Snipers, it's there that the similarities end.
"It's probably more of a passing game and there's no body contact [like] you get in ice hockey so no, you don't get the fights," says New Zealand Inline Hockey National Champs tournament director Krystyna Beardman.
The championships have been running every year since 1996 and this year's tournament held at Hamilton's inline hockey rink at Lugton Park features 50 teams across eight divisions.
Ms Beardman says despite a lack of facilities and some of the costs involved in playing, the sport is slowly gaining in popularity.
