A terrified elderly couple say they were forced to cower inside their home after their abusive Kāinga Ora neighbours held a Black Power party at which a police officer was allegedly assaulted and a reveller tried to steal a patrol car. 

As the party kicked off on Saturday night, police advised the Whangārei couple to stay inside their neighbouring Kāinga Ora property for their own safety. 

Patched gang members boozed from hours of drinking allegedly crashed a car outside the property and urinated in their shared driveway while shouting obscenities as officers dealt with the disorder. 

Kāinga Ora admits it was aware of the planned gathering but says it was powerless to stop it, instead advising neighbours to call police with any concerns. 

"It was horrific," the 69-year-old wife told the Herald. 

"I was a mess. I was shaking like a leaf." 

The Herald reported last week how the couple had been subjected to death threats by one of the tenants - a Black Power gang member who allegedly threatened to slit the 82-year-old husband's throat and watch him "bleed out".
