It is not yet known whether the two incidents are related to seven attacks across the city on Tuesday night, linked to tensions between the Killer Beez and Tribesmen gangs.
Police were called to Vina Place in Massey about 7.30pm yesterday after reports a shot had been fired, and officers remained on site overnight.
About 9pm, police were alerted that a firearm had been discharged towards a house on Bleakhouse Road, Mellons Bay.
Officers were looking at CCTV images as part of the investigation, Detective Inspector Warrick Adkin Counties Manukau CIB said today.
No injuries had been reported by Thursday morning at either incident.
The shootings in the turf war between the Tribesmen and Killer Beez gangs warranted police officers being armed in Auckland, Police Association president Chris Cahill said.
He said there was a case for a general arming order in Auckland at the moment "given the number of incidents and the prevalence of them and how dangerous they are."
"I know a number of officers feel that should be the case."
Police - including gang liaison officers - could work towards restoring a truce but community leaders and whānau also had to be involved, he said.
"It's a matter of getting these people together to agree that this out of control, they're putting themselves at risk, their whānau at risk and the communities at risk.
"My biggest concern was that these groups end up confronting each other and having a shootout."
Police were seizing firearms, but there were so many out there it would take a long time to get on top of that, he said.
