Auckland, Jul 21 (IANS): The victims of a deadly shooting in Auckland were two men aged in their 40s, New Zealand Police confirmed on Friday.

The two victims worked at the construction site, which was the scene of Thursday shooting incident, alongside the deceased offender, 24-year-old Matu Tangi Matua Reid, who also worked there, Relieving Auckland District Commander, Acting Superintendent Sunny Patel said.

It remained unknown if the gunman, who had been on home detention on family violence charges, was shot by police or took his own life as the investigation proceeds, Xinhua news agency quoted the police as saying.

A scene examination will continue at the site of Thursday's tragic incident in the largest city of New Zealand, Patel said, adding CBD residents and workers can expect to see a continued police presence in the area as this work is undertaken.
