A REAL estate agent has pleaded guilty to sending poo in the post to a work rival—but has told a court that the stool wasn’t his.

The New Zealand Herald reports Grant Campbell Tucker originally denied the 2014 allegation and was due to appear in Auckland District Court yesterday on charges of posting a noxious substance and using a telephone to offend.

However, the court confirmed the 58-year-old had pleaded guilty to the faeces charge and would not be back in court until June.

The second charge of using a telephone to offend has been dropped.

It’s believed the incident was a result of a long-running dispute between two rival real estate agents, Tucker, a director of Netrealty and John Charles Wills, who is a director of Custom Residential.

“It’s not about turf, it’s about ethics, integrity and honesty,” Tucker said in an email sent to NZME when the original charges were laid.

Tucker had previously said that he worked at Custom Residential and was owed commission.

Defence lawyer David Beard said his office received a box in a courier bag along with a letter with Tucker’s company letterhead.

“It was opened on the steps of the Auckland Central Police Station with myself and a constable and ... I was gagging over the side, with tears in my eyes.

“I’d just been to the High Court that morning, so I was all dressed up in the black suit, the works, with hazmat gloves.”

Tucker admits sending the package but his lawyers say he was returning the package to its sender and that the faeces didn’t belong to him.

“So ‘whose poo is it?’ is a good question and why are they not charged?” his lawyer Ron Mansfield said.

“In 16 years I’ve never seen anything like this in my career, and I have to deal with some interesting people,” lawyers for Wills added.

The mystery of the real estate poo continues.
