The second incident occurred around 1am on July 3 when multiple shots from a high-powered rifle and a shotgun were fired at an address on the corner of Elizabeth St and Elles Rd.
There was one occupant in the house at the time but they were not injured in the shooting.
Police believe the house was incorrectly targeted.
Shortly afterwards, officers spoke to the occupants of two vehicles on Ball St, who both had Mongrel Mob gang affiliations.
“Since these incidents occurred, police have been carrying out a number of inquiries and we believe offenders for both incidents are associated to the Mongrel Mob gang,” a police spokesman said in a statement.
A vehicle of interest in both matters was recovered in a recent search warrant at an Invercargill address.
“This is quite a distinctive vehicle and police are appealing for sightings of the dark-coloured Toyota Sienta around those times. These vehicles have very distinctive tail-lights.
“We acknowledge that these matters were some time ago but want to highlight the seriousness of this type of offending and the impact it has had on our victims and members of the public who live in these areas,” a police spokesman said.
“Police are following lines of inquiry and want to assure the public that we are continuing to investigate both incidents and are committed to holding those responsible to account.
“We believe there will be people out there who have information relevant to our investigations and encourage anyone with information to please contact us and know that you can do so in confidence.”
