All shipping is currently on hold in Port of Tauranga after a log carrier's engine failed while leaving Tauranga Harbour.
The China-bound log carrier lost power at about 12:30am on Monday.
The Singaporean-registered vessel, Funing-9690913, is anchored in the shipping channel between Mount Maunganui and Matakana Island.
Two Port of Tauranga tug boats and the Tauranga Harbourmaster are in attendance and providing support, Maritime New Zealand confirmed in a statement.
No oil or other pollution has leaked from the vessel, said Maritime NZ deputy director of safety and response systems, Nigel Clifford, and all 21 crew aboard - including a maritime pilot from the port - are unharmed.
A response centre has been established by Port of Tauranga authorities to manage the event. A team has also been formed to provide coordination and support.
Weather and sea conditions at the time of the engine failure were relatively poor, Maritime NZ noted, with a significant swell and 30-knot wind. However, the wind and swell are set to improve throughout the day, according to Monday's forecast.
In an update shortly after 10am, a representative for Port of Tauranga confirmed the log carrier is being moved away from land to deeper water in the shipping channel.
The vessel is believed to have made contact with a marker buoy, so divers will check the Funing's propeller and rudder before any attempt is made to restart its engines.
As of 10:15am, shipping remains suspended at the port. Updates will be provided as further information becomes available.
