New Zealand Police have cordoned off several streets in Auckland’s CBD as they respond to a serious unfolding incident involving a reported gunman.

St John Ambulance have confirmed two injured people in a Thursday morning attack.

Local outlet Newshub reports a police officer is among the hurt.

A heavy police presence, including armed officers and helicopters, has responded to what police called a “significant incident with multiple emergency services responding.”

“The serious incident in Auckland CBD this morning is currently contained to a building in lower Queen Street, which is under construction,” a statement read.

“Police ask all members of the public to avoid the lower Queen Street area and for those in downtown inner-city buildings to remain inside their buildings at this time.”

Locals reported hearing gunshots about 8am, with media broadcasting workers at the building site hiding behind packs of pre-mix cement under police supervision.

Ferry services, which use a nearby terminal to operate, have been cancelled.

The incident has taken place as Auckland prepares to host the opening game of the Women’s World Cup later on Thursday.

The FIFA Fan Festival is nearby, with former NZ international Maia Jackson telling the NZ Herald she was nearby.

“It’s pretty scary actually. So they pushed us to the back of the cloud where we are and we’re just trying to keep sane,” she said.

“There’s lots of security and lots of uncertainty.”
