The Otago Regional Council and the Dunedin City Council will
later this month begin consulting the public on new rules and

The two councils would take the new rules on the road in a
series of 11 community consultation sessions this month and
Feedback from those sessions would be used to refine the
proposed district plan rules and standards for those areas.
The hazards information was also being used to inform the
Otago regional policy statement, which sets out a policy for
managing the region's resources into the future.
It was recommended the reports were noted, endorsed and
provided to the DCC.
