The government has an obligation to ensure that New Zealand ports provide adequate facilities for the disposal of the various waste products generated onboard ships.
This obligation arises under MARPOL 73/78; the International Convention on Prevention of Pollution from Ships.
Port facilities can be fixed or mobile. Fixed waste facilities include those normally found at oil terminals to receive tank wash from oil tankers. Mobile facilities include road tankers operated by private waste removal contractors.
To assist ship operators to comply with the MARPOL 73/78 Convention, Maritime New Zealand and the Australian Maritime Safety Authority (AMSA) publish biannually a list of shore-based facilities that are available to dispose of ship-generated waste.
Wherever possible, arrangements for the use of port reception facilities in New Zealand and Australian ports should be made through the ship's agent. Charges usually apply for the use of port waste facilities.
