A homeless woman was taken to Rotorua Hospital after she was seriously assaulted at the Rotorua Recycling Centre.
Rotorua Senior Sergeant Karl Konlechner said a homeless man and woman, who were said to be a couple, had a domestic fight about 11pm on Thursday at the recycling centre.
He said the woman was seriously assaulted and needed hospital care. It was not known whether she had since been released from hospital.
Mr Konlechner said the man, who was known to police, was arrested and appeared in the Rotorua District Court yesterday.
When The Daily Post arrived at the recycling centre about 8am yesterday a nearby driveway had been cordoned off by police.
A shopping trolley with empty alcohol bottles and a blood-stained couch could be seen on the blocked-off driveway.
A worker from the Urban Ore store next to the recycling centre, who did not want to be named, said people often left donations for the store in the covered driveway where the assault took place.
He said the area often attracted homeless people who would spend the night there.
He was shocked to see the blood-stained couch when he arrived at work.
He said a handbag which had blood on it had been left at the front door to the store as well as one shoe.
"I hope the people involved are okay," he said.
