At the northern end of Lake Rotoiti, St Arnaud is the gateway to Nelson Lakes National Park. Approximately 120 people live in St Arnaud. The village has a small commercial centre, school, outdoor education facilities and community hall. The Alpine Fault crosses the village and a significant earthquake may cause other hazards such as liquefaction, lake tsunami (seiche) and landslides. The area is also vulnerable to flooding and wildfire.
- There is a risk that additional development in St Arnaud (including Tophouse / Wairau Saddle) will have adverse effects on Nelson Lakes National Park, including loss of natural and rural character.
- The wider area is vulnerable to a range of natural hazards.
- As St Arnaud grows and changes, there is a risk that it can lose its distinctive sense of place, identity, and character.
- Land currently zoned for commercial use is all taken up.
- Continue to protect the natural environment and ensure that the built environment blends in and enhances the surrounding environment.
- Continue with appropriate residential lot sizes in St Arnaud village to maintain the area’s natural character.
- Enable a limited amount of new residential growth in specified locations, recognising natural hazards and natural landscape constraints.
- Implement the Future Development Strategy which provides for rural residential opportunities on Korere-Tophouse Road.
- Retain a clear rural character which avoids ribbon development between Tophouse junction and St Arnaud.
- Promote consolidation of commercial services and tourist accommodation near the centre of St Arnaud.
- Support landscape and streetscape initiatives that contribute to the character and amenity of the commercial centre of St Arnaud.
