The search is still on for wanted man Ross Douglas Bremner, after a woman was killed and a man critically injured in a stabbing attack in Otorohanga on Tuesday night.
Armed police have been searching in and around the town, focusing on an area of Otewa Rd and Mangawhero Rd on the edge of Ōtorohanga on Wednesday night.
The victims are understood to be Bremner's parents. His mother, 60, died at the house where the attack happened at 8:30pm on Tuesday. Bremner's father, 64, is in intensive care at Waikato Hospital.
Detective Senior Sergeant Ross Patterson says Bremner should not be approached, and also warned that people in the Otorohanga area can expect to see members of the Armed Offenders Squad.
"They are being used as part of the Police investigation and have visited a number of properties in an attempt to find Mr Bremner," Det Snr Sgt Patterson said.
"Today, in addition to gathering information, staff continue to examine the scene where the female was found deceased."
The post-mortem examination on Mrs Bremner's body is expected to be conducted on Thursday, and Waikato Hospital said Keith Bremner remained in a critical condition on Thursday morning.
Det Snr Sgt Mark Greene says it's too early to know the exact nature of the attack.
"We haven't examined the scene yet and we will have a post-mortem in Auckland," he said on Wednesday.
"Those are still details we're putting together."
Det Sen Sgt Greene said police were not certain whether Bremner was still in the Otorohanga area.
He said Bremner could be driving silver Holden Vectra, registration BGP561, "but we're not absolutely convinced about that either".
"He may be in another vehicle or he may be without a vehicle," he said.
"There's a whole number of possibilities we're looking at."
No weapon has been found.
The Waikato District Health Board has confirmed Bremner has been a client of its Mental Health and Addiction Services.
He last had a period of inpatient care in 2013 and has been living in the community for the last three years, the DHB's executive director Lydia Aydon says.

Detective Senior Sergeant Mark Greene says Bremner lives at the address and is known to the victims, but would not confirm they were related.
He says he wants to assure the town's residents police are taking all measures to find the man.
"We want to send a message to the community that police has taken steps to ensure all is being done to keep people safe while we investigate this matter.
"However, if any local person has any concerns, they should not hesitate to call police."
He says a neighbour had alerted police to the incident. Indications show it was a knife attack, he says, but he couldn't confirm if a weapon had been found.
