Bullet holes in the rear windscreen of a car on Keegan Drive, Massey after a second firearms incident on Tuesday.
Police investigating two firearm incidents on a West Auckland street are now treating them as linked.
However, another incident in a nearby suburb which was at first believed to have involved a gun, was not thought to be related.
Two people were taken into custody after the first incident on Keegan Drive, Massey, about midday on Monday. The incident forced a primary school into lockdown.
Both people were spoken to and one had been arrested on an unrelated matter, police said.
* Two people in custody after incident which saw West Auckland school locked down
* Lockdown lifted at West Auckland schools, police speaking to person
* Eight shots fired overnight at same Auckland address that sparked school lockdown
On Tuesday, a further eight shots were fired at vehicles outside the address about 2am.
Armed police descended on the address again and searched it, but no one was found.
Detective Senior Sergeant Megan Goldie, Waitematā Criminal Investigation Branch, said on Wednesday afternoon they believed the incidents were connected.
Although police continued to investigate all parties involved, no charges had yet been laid, she said.
A scene examination at the property had been completed.
“Police have increased its presence throughout the Massey area since this week with additional patrols.”
Leisha Byrnes, principal of Lincoln Heights School, said on Monday police advised the school to go into lockdown around midday on Monday.
It was the second time this year the school had been placed into lockdown after it was locked down in July following the shooting of Constable Matthew Hunt, which happened only a few hundred metres away.
A police cordon was lifted shortly before 2.30pm, and parents were allowed to pick up their children from school.
On Tuesday, armed police were called to a possible firearms incident on nearby Archibald Rd, in Kelston.
That incident also triggered a lockdown of several nearby schools.
A police spokesman said a report of concern for a person’s wellbeing had been made after 2pm on Tuesday in the area and that a fire arm may have been involved.
However, police found the person involved later that night. The also discovered a BB gun.
The matter was not believed to be linked to the Massey incidents and has been referred to Youth Aid.
“We would like to acknowledge the co-operation of our schools and community while we carried out our inquiries in the Kelston area,” acting area commander for Waitematā West Inspector John Thornley said.
