The pig got loose down the main streets of Waihi.

KFC was used to corral a large boarish pig on the loose through Waihi streets.

The estimated 150kg hog hit the pavements of the Waikato town late Sunday night, sparking an emergency response.

"We got into a pursuit with a pig," Waihi police Constable Harley North told Gold FM on Tuesday.

North was unable to say how the swine got loose, believing it was likely someone's pet that had broken out.

It ended up on the trot down one of town's main streets with police in hot pursuit.

As luck would have it, staff at a nearby KFC came to the rescue, along with St John ambulance officers who happened to be nearby.

Using finger-licking good KFC chips and a few hot bread rolls the group managed to wrangle the beast.

"They fed it KFC chips and bread rolls to distract the pig and stop it running down Seddon St."

After sometime the pig was corralled into a makeshift pen at the local Presbyterian church.

"The pig was left to contemplate his sinful behaviour," North said.

On Tuesday morning the pig was spotted being escorted by a "tall dark stranger" down the Waihi street.
