Hone Kay-Selwyn was found dead near Taupō on May 8 this year, three days after fatally shooting 33-year-old Robert Sidney Horne.
A firearm was not found with Kay-Selwyn, a member of the Killer Beez gang, and no shell casings were recovered at the scene of the shooting.
Detective Inspector Chris Barry said today that police were undertaking forensic testing of the two pistols to establish a link to the Ponsonby shooting.
They are continuing to work out how Hone Kay-Selwyn obtained the firearm, he added.
The New Zealand Herald reported the pistols were cut-down Alfa carbine rifles, popular with criminals because they do not leave behind shell casings, which can be used as evidence.
