An unemployed Nelson man has admitted urinating and masturbating in the lounge of a stranger's home then falling asleep on a couch with his trousers around his ankles.

Jason Ernest Gambitsis, 38, admitted charges of intentional damage and procuring cannabis when he appeared in Nelson District Court yesterday.

Police prosecutor Sergeant Wayne Johnston said that on Saturday, June 13, Gambitsis was drinking with family and friends at a hotel in central Greymouth.

While still drunk about 6am on Sunday he left the hotel and entered a residential address.

The female occupant was woken by noises and found him asleep with his pants around his ankles. He had urinated on the carpet and masturbated on the couch.

Judge Paul Whitehead remanded Gambitsis on bail to reappear for sentencing on August 11.
