The investigation team is appealing for sightings of a dark-coloured sedan believed to have been in the area at the time.
During a vehicle stop later that night, three gang members aged 18, 25 and 31 were found in possession of a firearm and ammunition, and have been charged with unlawful possession of a firearm and ammunition.
They are due to appear in Gisborne District Court on Wednesday 13 September.
The second incident occurred about 5:50pm on Mangapapa Road, Mangapapa on Thursday 7 September.
Police understand a firearm was discharged from a vehicle at a residential property in this incident too.
A silver Subaru is believed to have been in the area around the time of the incident and anyone who saw this vehicle is encouraged to contact Police.
A 25-year-old gang member was arrested this morning following a search warrant at a Gisborne address earlier this week and charged with the unlawful possession of a firearm.
