A car linked to a Matamata home invasion was found in Rotorua last night.
Eastern Waikato head of CIB Detective Senior Sergeant Graham Pitkethley said they were working with Bay of Plenty police.
He said the victim of yesterday's attack had been released from hospital and was recovering at home.
"A scene examination of the Sylvan Pl property where the 1.55am attack took place was completed yesterday as was the interviewing of witnesses and some persons of interest," he said.
"Overnight Police in Rotorua located a white Subaru Legacy of interest to our inquiry team and an examination of that car and an interview of the male driver are being conducted today.
"That being said, this was a serious assault and we would ask that those involved or anyone who knows the location of those involved make contact with police before matters escalate further."
Anyone with any information is asked to contact Mr Pitkethley at the Matamata police on 07 858 6200.
