Rival rugby codes in Greymouth have to tackle a rather hairier adversary than usual this year - an infestation of rabbits digging holes in fields and chewing up grass.
Marist Rugby Club spokesman Mark Costello has noticed a boom in the rabbit population which lives in the coastal strip between the pitch and the cycle trail.
"They come out to feed on our field," he said. "They eat the grass, and of course now there's a shortage of grass."
The rabbits seem to be causing more damage than usual in the newly-relaid field.
"They're very tricky to get rid of. We can't use poisons in that area."
