Shots were fired at a vehicle on O'Donnell Ave, Wesley, around 6.45pm. A woman received a minor injury to her arm but did not require medical attention.
Thirty minutes later, in nearby Mt Roskill, there were reports of a shotgun being fired but, on arrival, police found no damage at the property on Freeland Ave.
On the same night, a man received a gunshot wound at an "unknown location" in Sandringham and he was taken to hospital for treatment.
An earlier shooting on Haverstock Rd in Sandringham on Friday evening remains under investigation.
"These incidents will be extremely concerning to those who live in these areas, but we want to reassure our community that these appear to be targeted incidents between people who appear to be known to each other," said Pascoe.
A man, 38, has been charged with having a sawn-off shotgun in his possession and 10 rounds of shotgun ammunition when he was not the holder of a firearms licence at Mt Roskill on Sunday.
He is also charged with driving while disqualified on Memorial Ave, failing to stop for police, dangerous driving and dishonestly taking a vehicle.
He appeared at Auckland District Court on Monday.
Last month a person was taken to hospital after an alleged gang-related shooting in Morrie Laing Ave, Mt Roskill.
The shootings are among the latest in a spike in high-profile shootings that have rocked West Auckland suburbs in recent months.
A number in Glen Eden, Avondale, New Lynn and Blockhouse Bay have left residents feeling increasingly unsafe.
