But police have since confirmed there is no suspicious item on-board and no cause for concern. Cordons in place in the Aotea Quay area around the ferry terminal have been stood down.

"Inquiries are continuing as to the identity of the person who made the threat," police said in a statement.

There were 507 passengers and 84 crew on the ship, KiwiRail Chief Operating Officer Todd Moyle earlier told 1 NEWS.

A passenger, who wished not to be named, told 1 NEWS about 10 minutes into the journey the ferry turned around and all passengers were asked to go to the top level of the ship due to a security threat.

Once they arrived back at port, all passengers were ordered to abandon ship and were directed to the passenger terminal.

Then all car drivers and truck drivers were separated and asked to hand over their keys so police could search their vehicles.

The passenger said everyone was calm as police made inquiries on board the ferry.
