An exercise this week will test how the Otago Civil Defence Emergency Management Group deals with a major snow storm.
The scenario, to be tested on Tuesday, is of a snow storm affecting most of Otago, with road closures, disruption to power and telecommunications, and rural communities cut off.
Otago Civil Defence coordinator Scott McNaughton says the exercise will test the effectiveness of emergency management in Dunedin, Oamaru, Alexandra and Queenstown.
In particular, it will focus on coordination and communication between the groups.
The exercise will be held over four hours and will not affect the public.
