What can we help you with?

  • Archaeological Assessment. An archaeological assessment is required for an authority application 
  • Heritage Impact Assessment. An HIA is often required for a resource consent where the property is scheduled on the District Plan.
  • Conservation plan. A conservation plan identifies the significance and heritage values of a historic place in order to create policy and recommendations of how to conserve, manage and care for it.
