A Navigational Risk Assessment (NRA) for Wellington Harbour was first undertaken in 2006. This 2017 NRA represents a fundamental review and update of this record. Much has changed to harbour risk in the interim years; harbour use has grown significantly with large volume increases in cross harbour ferry commuter services and further increases in the level and types of recreational activities occurring on the water. The Harbour Risk Assessment details by hazards are available electronically online in the GWRC Hazman II risk management package.
