"We need to insure that people in any part of our city are safe and feel secure – and having that number of shootings in South Auckland is a very high level."

"It is about listening to the community about what else needs to be improved so they have a greater feeling of security," he said.
Goff said a lot of the recent shootings in the area had been related to gang competition and the trafficking of drugs.
"I have been in touch directly with the Minister of Police and he is putting more police officers on the ground into Otara as they graduate from the new intakes, and the police are putting a whole lot more emphasis on cracking down on organised crime – and effectively drug trafficking through gangs is a form of organised crime.
"We need to lift those efforts, and I've had very reassuring comments coming back to me from the Minister of Police about what he intends to do to lift our resources in South Auckland."
