Proposed new rules designed to protect Dunedin from
natural hazards could also lower property prices in some parts
of the city, the Dunedin City Council says.
Details of the new approach - which was set to be released
for public consultation - were unveiled at a council media

Local knowledge would be "very important'' to refine the
process, and the council wanted to know if it had struck the
