The Chisholm Park golf course is being damaged by a plague of rabbits, leaving burrows and scrapes all over the course.
On Monday evening, club president Ross Clough shot 25 rabbits but he admitted this was just scratching the surface.
Mr Clough said he intended to have another shoot tomorrow evening, subject to weather conditions.
''I use a 22 calibre rifle and a spotlight and all of the shooting is done within the regulations,'' he said.
''We have to put signage up to warn of danger to members of the public who might be walking on the course and notify the police of every shoot.''
Course superintendent Darrin Steedman has used water hoses to try to flush the rabbits out of large burrows.
But Mr Clough said that was time-consuming and the greens staff had many other tasks rather than filling in holes all day.
''There have always been rabbits around, but this year there are many more, including a lot of young ones,'' Mr Clough said.
''We want to eradicate as many as possible, as [the burrows] are unsightly and can be dangerous as you have to watch where you are walking.''
Under the rules of golf, if a player's ball lands in a rabbit burrow or scrape, golfers can get a free drop to the nearest point of relief.
However, the deep burrows and hundreds of scrapes at Chisholm Park detract from the presentation of the course, which provided excellent greens and tees for the New Zealand Open qualifying event yesterday.
