A woman tried to "talk down" a gunman before he was shot dead by police in Upper Hutt this afternoon, her boss says.
Armed police were sent to Main St after receiving reports of a man with a firearm outside the town's McDonald's restaurant about 12.40pm.
A police statement said the man aimed the firearm at officers and was shot. He died a short time later despite immediate medical attention.
No one else is being sought in relation to the incident and police said the public can go about their business safely.
Officers are still establishing exactly what happened and speaking to a large number of witnesses, the statement said.

Tony Loveday, who owns the Skynet City Stop opposite McDonald's, said a woman who works for him tried to talk the gunman down.
The woman, who does voluntary rehab work with prison services, was in the street with the man, Mr Loveday said.
"He had a rifle in his hand. He kept going forward and back.
"She was trying to talk him down. She said she had a good liaison with him. He was going to put the rifle down. She was only a metre away when he was shot dead.
"She was pretty adamant he was going to give himself up. She didn't know him. She said he told her he was trying to get into the army and was rejected because of his police record."
Witness Ugur Kokcu saw the woman talk to the gunman for a couple of minutes.
The gunman was animated at times. The rifle was mostly by his side but when he raised it slightly, he was shot twice by police, Mr Kokcu said.
Subway worker Nikki Hearfield said the gunman looked like he was in his late 20s.
"He wasn't holding the gun aggressively. It was just in his hand to the side."
She heard police fire two shots.
Superintendent Sam Hoyle said he could not comment at this stage on suggestions the gunman was being talked down.
"On arrival police staff were fired upon. They have spoken with the man involved and attempted to negotiate a peaceful resolution. After some minutes he has been shot by police. He has then been offered medical support by both police officers and Wellington Free Ambulance staff. Unfortunately he has died at the scene in what is a tragedy for everyone involved."
Mr Hoyle said police had informed the man's next of kin were being informed.
They and the officers involved were offered support.
Nobody else was injured and a police dog released at the scene was also fine.
Mr Hoyle said the man was brandishing a "high-powered" rifle.
Wellington Free Ambulance spokeswoman Di Livingston said two ambulances were sent to the scene but an off-duty paramedic was first to reach the shot man.
"We attempted to resuscitate a man but weren't successful," Ms Livingston said.
No one else needed treatment or was transported by ambulance.
McDonald's spokeswoman Kim Bartlett said the store was "now officially a crime scene".
"All our staff are safe and no customers have been hurt," she said.
"That's really all I can say. You will need to speak to the police about that."
At 2.30pm about 20 officers were still in the area and a large part of Main St remained cordoned off.
A police photographer was taking photos of what was believed to be the body, which was behind a parked police car.
Deborah Hawkins, who works in a nearby business, said she heard three shots in total, the first about 12.45pm.
"And then about 20 minutes after that we heard about two more shots. We could see the police outside our window with guns running up down the street."
Vasely Sapunov was in his car on Main St when he saw three people run past with shopping trolleys.
He saw a police car with sirens blaring and decided to start live streaming on social media video site Periscope.
"I thought it was a bit of a laugh ... some kind of low-level theft... so I started live streaming it," he said.
"Then heaps and heaps of cops started storming the street. Officers were screaming for people to get in the buildings... the street started to empty out. There wasn't anyone anywhere."
Nearby St Joseph's school went into lockdown briefly but was told about 1.35pm that the situation was safe. A spokesman said it was lunchtime when the alarm was raised so bells rang and the children went briefly back into their classrooms.
Police Association President Greg O'Connor said today's shooting was the fifth time in a month frontline response police officers have had to deal with "armed and clearly dangerous offenders".
"This afternoon's incident in Upper Hutt follows similar incidents in Palmerston North, Hamilton, Raetihi and Motueka, all in the last month," he said .
"In each of these incidents, the officers involved have been required to take immediate action in situations governed by the actions of armed offenders."
Mr O'Connor said police bosses and the Government had given "constant reassurances" that armed incidents were not the result of changes in the criminal world. He said it showed top brass were "out of touch".
He said the incidents had occurred at a time when the numbers of frontline police deployable to such incidents were being reduced due to funding issues.
"The Police Association on behalf of its members asks how many such incidents it will take before the changing nature of the policing environment is acknowledged by authorities," he said.
"The Police Association will fully support the officers involved in the shooting, and we ask that those who wish to comment on the officers' actions should await the outcome of the properly conducted and intense inquiries that will follow today's incident."
A spokeswoman for Police Minister Michael Woodhouse said it was "very much an operational matter and we have no plans at this stage to make any comment".
This is the sixth high profile incident involving firearms in a month.
