A New Zealand man has been sentenced to community service after telling police he had been raped by a wombat and the experience had caused him to start speaking "Australian".

Arthur Cradock, a 48-year-old orchard worker from Motueka on South Island, rang police on February 11 to say he was being raped by the slow-moving Australian marsupial at his home, The Nelson Mail reported.

He rang back soon afterwards to say he was withdrawing his complaint against the wombat, a court was told.

"Apart from speaking Australian now, I'm pretty all right you know," he told police in the second call.

Cradock pleaded guilty to using a phone for a fictitious purpose and was sentenced to 75 hours community work.

Prosecutors said alcohol played a large part in Cradock's life, although his defence lawyer said he was not drunk on the afternoon of the phone calls.
