The man at the centre of an armed standoff with police in Napier last month had consumed "a large amount of methamphetamine" destined for a drug deal - and used his pregnant partner and baby as a "shield" to protect himself from gang members he thought were out to kill him over the missing drugs.
Hemi Taylor, 25, pleaded guilty to two firearms charges after a tense 12 hour stand-off with police at his home in Alexander Avenue in the Napier suburb of Onekawa on June 23 and 24.
The incident sent nearby schools into lockdown for several hours, closed roads and prevented dozens of residents from being able to return to their homes that night.
"During the evening of June 23 he became extremely paranoid believing that the Mongrel Mob were looking for him in order to kill him due to the missing drugs."
Earlier that afternoon, armed with a shotgun cut down to pistol length, he and his partner of seven years and their 4-month-old daughter visited her mother in Napier.
"He paraded the firearm around the house before going outside and firing it at a fence yelling the gang slogan 'Sieg heil'," the police report said.
After arguing with his partner over the baby, he grabbed the child and took her with him in the car with the firearm. Returning to the address a short while later he picked up his partner and drove to their home in Alexander Ave.
By this time police had been alerted and had located his car parked in the driveway.
"The defendant was in the house with the firearm and was using his partner and baby as a shield in case the Mongrel Mob were out to get him."
With police realising this would likely become a protracted incident, the area was secured with cordons and schools were put in lockdown. The Armed Offenders Squad was dispatched and a strategic tactics group from Wellington was flown to Napier from Wellington by helicopter.
"At about 1.30pm on June 25 after 12 hours of the area being shutdown the defendant agreed to surrender and was taken into custody."
It is understood he emerged from the house carrying his 4-month-old daughter.
"The defendant's partner was spoken to by police but declined to make any complaint," the report said.
Police later found a single-barrel shotgun, cut down to pistol length - with one cartridge still in the barrel - wrapped in cloth and hidden in drawers.
Taylor did not have a firearms licence and "had no reasonable excuse for being in possession of a firearm".
"In explanation the defendant stated he did not have anything to do with a firearm."
Taylor pleaded guilty to charges of unlawful possession of a firearm and discharging a firearm at Napier District Court on July 17.
He will be sentenced in Napier District Court on August 27 - a few weeks after his 26th birthday.
Police would be seeking reparation to cover some of the "several tens of thousands of dollars" cost of responding to the incident.
The police, fire and St John Ambulance personnel spent considerable time at the incident, estimated to be in excess of 400 hours.
The cost of the man hours involved is in the region of several tens of thousands of dollars. Other resources include helicopter time, which has also consumed a large cost, again estimated to be in the thousands of dollars.
Court documents show Taylor has 28 previous convictions since 2010 including assault, threatening to kill, possession of a weapon and aggravated robbery.
