The Maritime Transport Act 1994 is one of the main laws governing maritime activity in New Zealand. It sets the framework for safety, marine protection, maritime documents, inspections, investigations, offences, levies, local navigation controls, carriage of goods by sea and the powers of Maritime New Zealand and its Director.
For a business owner, the practical point is that the Act is a framework law. It creates broad duties and enforcement powers, then relies on maritime rules and other instruments to set many of the detailed operating requirements. So compliance usually means checking both the Act and the specific rules that apply to your vessel, operation, crew and route.
