Dogs generally cop the blame for breaking into rubbish bags left on the side of the road for collection by Waste Management, but it was pigs that made a mess on Kohumaru Rd, south of Mangonui, last week.
And resident Mike Crossley said he had had enough of people who put their bags out earlier than they should.
"Everyone knows that the bags are picked up on Tuesday, but that doesn't bother some people," he said.
"They put their bags out when they feel like it, and that's just inviting animals to break into them and spread everything around.
