A 21-year-old man has been charged with murder following the death of Siaosi Tulua in April.
Mr Tulua, 39, died of gunshots at his home on Darnell Crescent, Clover Park, on 20 April.
Earlier this month a 22-year-old man was charged with his murder.
Now, a second man has been charged with murder and is due to appear in the Manukau District Court today.
Acting Detective Senior Sergeant Kepal Richards said police are still seeking information about the murder, despite charging two people.
"Even four months after Mr Tulua was shot and killed, our detectives continue to piece together the events surrounding his death."
Mr Richards urged anyone else with information to contact Counties Manukau Police on (09) 261 1321 or Crimestoppers anonymously on 0800 555 111.
