Two stray bullets found in a community house after a shooting involving police and an armed gunman in Christchurch were likely fired by a "panicked" officer.

Avebury House manager Tanya Didham says it's pure luck the incident didn't happen on a different night, as the room that was shot at would have been in use for yoga classes.

The gunman had been on the run from police after allegedly firing at police days earlier.

He was again spotted on Tuesday night when they became involved in a dramatic police chase across the city.

Police signalled for the man to stop on Anzac Drive, in the eastern suburb of Wainoni, just before 1am.

He took off, with police alleging shots were fired from the window of his car and the pursuit was abandoned.

They came across the man's car again on Breezes Rd before it was road spiked, coming to a stop on Eveleyn Couzins Ave in Richmond.

At that point an alleged shootout began, with bullets being exchanged by both parties and the accused shot twice in the lower body.

However, unbeknown to police, two stray bullets landed inside Avebury House where users were having a meeting in a downstairs room.

Manager Tanya Didham said she'd been told by police the officer who fired the wayward bullets was likely "panicked" by the volatile situation unfolding.

On the night she got a phone call from a security guard saying "there's loads of sirens and fireworks going off at the house".

"Turns out it wasn't fireworks," she said.

She discovered the bullet holes the following morning when she went into work.

"I was on the phone to one of the board members and she said 'you better check the house for bullet holes' and I'm going 'haha very funny'. And then I went into the upstairs Koro Wilding room and thought 'oh wow, why is there glass all over the floor' and then saw there was a bullet hole in the window."

A second bullet hit the adjacent shed which is separated from the building by their driveway.

Avebury House is a community house where various events or classes are held, including yoga. The upstairs room is where yoga classes are regularly held.

"That's quite a common time for people to be using that space. Yoga is there on a Thursday night and we often have people that are doing wellness or meditation seminars. We give them that room because it's the most peaceful, but not on that night it wasn't.

"It doesn't get used every night ... but it was lucky, very lucky."

She said it was simply "fortunate" there was no there, "otherwise it could have been really pretty awful".

"It was kind of frightening. The gunman was facing away from us, the police were facing directly towards the house and when they opened fire obviously we became part of the line of fire."

She said officers would not have known there people in the area at the time as it was "such a high pressure, high adrenaline, high risk situation".

"They were just acting on adrenaline really."

She had spoken to police who told the officer had mostly likely "panicked" and completely missed his target.

"The officer that I spoke to said that he would have been just a bit panicked and he's just fired.

"The gun's either recoiled and it's fired or they were just freaking out themselves, no doubt.

"It indicated to me that the line of fire was really wide and there were a lot of bystanders in that area that they didn't realise.

"To put a bullet in the Cora Wilding, he was definitely not on target."

The building had been cordoned off until earlier today as forensic teams scoured it for bullet fragments or shells. That meant their two weddings scheduled for the weekend could go ahead as planned.

Didham added that she didn't want to come across as though she was criticising police, as they were working in a volatile situation, but suggested they could do with more training.

"I just think they are under-resourced, which means weapons training maybe isn't as comprehensive as it could be. [I'm] just so relieved no bystanders were hurt.

"The police have been brilliant, really approachable and helpful."

As a way to lighten the atmosphere in the neighbourhood, Avebury House had decided to host a "community barbecue" on Tuesday night.

"We thought we'd have a bit of a community get together and shake off the tension. The police are all on board with that ... they're going to contribute to that and Housing NZ people will also contribute as well."
