Wallace-Loretz called Corrections after he left the house, Mr Beard said.
Police said they were notified by the security company that monitors e-bailees that he had absconded before 11pm yesterday.
Police believe only one associate collected and drove Wallace-Loretz from the Avondale address before he cut his anklet.
Mr Beard said police had spoken with the associate and part of the investigation would look into whether anyone who had assisted or harboured Wallace-Loretz would be charged.
Border authorities had been contacted by police to ensure the murder accused did not leave the country. Mr Beard said he believed Wallace-Loretz had a current passport.
A police team of about seven is speaking with family and associates of Wallace-Loretz tonight.
A spokeswoman for Mr Gillman-Harris's family said the incident made the family feel like they were reliving the murder.
"We only found out an hour or so ago so we're still taking it in," she told One News today. "It feels like it did when this all happened the first time."
She said police told Mr Gillman-Harris's family they were taking the issue seriously and doing everything possible to find Wallace-Loretz.
Wallace-Loretz was jointly accused with Leonard Nattrass-Berquist, 17, of murdering Mr Gillman-Harris on December 27 at the Ascot Epsom Motel.
Sensible Sentencing Trust founder Garth McVicar said the debacle highlighted the stupidity of granting bail to people accused of murder.
"It's got to the stage where these failings are just about systemic ... there are so many. We could talk about Christie Marceau. The guy was on bail when he (killed) her," Mr McVicar said.
He said lawmakers were unwilling to tighten rules around murder-accused defendants being bailed.
"Parliament seems to be namby-pamby when it comes to this legislation and it seems to be all focused on ensuring the rights of the [defendant] rather than ensuring the rights of the law-abiding public to be protected from them."
He said there were "huge concerns" about granting bail to somebody like Wallace-Loretz who police today warned was dangerous.
The incident was a drain on police time and resources, Mr McVicar said.
"Surely that money would be far better [spent] with the police doing the job they're paid to do, and catching criminals, rather than having to go and chase [people] they've already caught who've absconded because of some liberal judge who's given them bail."
Private investigator Julia Hartley-Moore said the teenager probably did not have enough resources to leave the country.
She said the main concern for police would be if Wallace-Loretz had no money, he may become desperate and do something foolish.
Ms Hartley-Moore said police would have "a good handle" on who the teen's associates were.
Posts from a Facebook page ostensibly belonging to Wallace-Loretz indicated he felt a mixture of anger with authorities and optimism about his future.
"...Bro, won't be long I'll be back and rollin' in no time G," he told a friend.
The escape comes just nine days after the head of Corrections told MPs too many high risk prisoners were allowed out on temporary release.
Corrections chief executive Ray Smith told Parliament's law and order committee up to 10,000 names were added to a Customs border control system after the embarrassing escape of murderer and child molester Phillip John Smith.
A Customs spokeswoman was unable to immediately confirm if the agency was alerted to Wallace-Loretz being on the run.
Police warned anyone who may be continuing to help Wallace-Loretz that they will face criminal charges if they harbour him.
Wallace-Loretz and Nattrass-Berquist went to police on New Year's Eve after their names had been released to the public in relation to Mr Gillman-Harris' death.
Two days later, they were charged with murder and made a brief court appearance at Auckland District Court.
At their next appearance the following week, two further charges were laid against each of the youths.
They are also accused of robbing Mr Gillman-Harris of cash, a cell phone and bank card as well as unlawfully taking his $15,000 Range Rover.
Both pleaded not guilty to the charges on February 4.
A four-week trial has been set for November.
Both were ordered serve a 24-hour curfew with family members - Nattrass-Berquist on the North Shore and Wallace-Loretz in West Auckland.
