Coastal land and baches on the west coast: hazards, access and services

Short answer. Coastal land brings views and a lifestyle, but also hazards, remote access and limited services. Check council hazard mapping, ask for a LIM, ask about insurance before you commit, and check how water and wastewater work on the site. Mokau, Awakino and Marokopa have mapped erosion and flood hazard areas.

Hazards on the Waitomo coast

Waitomo District Council identifies coastal hazard overlays for Mokau, Awakino and Marokopa. CEHA 1 covers areas likely to be affected by erosion within 50 years. CEHA 2 covers the following 100 years to 2120, including 1.0 m of sea-level rise. CFHA covers rare extreme storm-surge flooding. Development is reduced in these zones, especially CEHA 1 (WDC, checked 2 Nov 2026).

In Ōtorohanga District, Coastal and Landscape Policy Areas and natural hazard areas can restrict subdivision (ODC).

Checklist

1. Ask for the hazard maps and a LIM. See LIM vs PIM.
2. Ask your insurer about cover, excess and any conditions.
3. Ask your lender about their policy for the property.
4. Check access: road, bridge, slip and flood history, tide.
5. Check water and wastewater. See water takes. Kāwhia township has no public sewerage.
6. Check power and phone.
7. Check what can be built. See subdivision rules.
8. For a coastal farm, check the usual items in shortlisting and the due diligence checklist.
