In recent years, terms like flooding, climate change, harbour inundation, and coastal erosion have become increasingly relevant—especially when planning projects in places like Mount Maunganui and Papamoa. Thanks to updated national flood mapping, future water levels are being forecast more accurately + increasingly higher, and in some areas that’s making consents a tougher challenge. The result? Even in relatively developed zones, navigating flooding-related rules can feel daunting.
National Guidance vs Local Reality
MBIE has produced useful flowcharts and guidance to help navigate natural hazard rules and the consent process. But once you’re dealing with your local council, things can play out differently. Territorial authorities may interpret the rules in their own way, and because some legislation isn’t black-and-white, this can lead to conflicting outcomes. Coupled with this, local site specific data often doesn't align accurately to GIS mapping.
That variability has genuine consequences:
- Minimum floor levels may be raised under the Building Code (E1) or Infrastructure Development Codes.
- A Section 72 notice might be placed on your property—triggered when hazards are present but cannot be fully mitigated.
- Insurance providers and future buyers often take note of any flood-related conditions—potentially affecting premiums and resale value.
How ata Helps You Navigate an Ever-Changing Landscape
At ata, we’re always on top of the latest updates in mapping, legislation, and council practices. Whether you're building new or making alterations, our experience equips us to find the right path forward—even when the term 'mitigation' alone feels vague.
Mitigation isn’t one-size-fits-all. We explore a range of tailored strategies, including:
- Raising platforms or regrading sites
- Shifting building footprints to safer zones
- Innovative architectural detailing that respects flood dynamics
- Working proactively with councils to craft practical, acceptable solutions
Each site is unique—and our project history reflects that adaptability.
Thinking of Building or Altering in a Flood-Prone Area?
If you're uncertain about how flooding, inundation, or erosion might impact your build—or simply want to understand your options—let’s talk. ata brings on-the-ground experience and local insight to guide you through the consent maze—even before you’ve drawn a single plan.
