A China Navigation Co (CNCo) multipurpose (MPP) has been detained in New Zealand after spilling oil on Tuesday.

The Hong Kong-flagged 1,728-teu Ningpo (built 1997) is moored at Northport in Whangarei following the incident.

Northport said good progress had been made during the afternoon on cleaning up the fuel. The amount involved is not yet known.

Workers are following the tide out to ensure that none of the spilled fuel remains on the beach, it added.
