Officers of the Armed Offenders Squad have peacefully resolved a five-hour stand off at a Hamilton house.
Waikato Senior Sergeant Phil Ruddell said the man started making threats to harm himself and police officers and the AOS arrived about 9.45am.
The man had been inside the house for almost five hours and was refusing to leave the property.
"A police negotiation team is present and talking to the person in the house and negotiating his surrender," Ruddell had said earlier.
