A house in Otara was invaded by three men - one of them armed with a sawn-off double barrelled shotgun - early on Sunday morning.
Two people from the house have been taken to Middlemore hospital with minor injuries.
Emergency services and the Armed Offenders Squad were called to the house in Nola Crescent at 2.15am on Sunday.
Police say no shots were fired and the men fled the scene.
One man has since been arrested and police are still looking for two others.
