Hawke's Bay Councils data via eolas

The Hawke's Bay region covers ~180,000 people. eolas serves 33 datasets from Hawke's Bay Regional Council (HBRC) and Central Hawke's Bay District Council (CHBDC), with comprehensive post-Cyclone Gabrielle hazard data. Napier City + Hastings District publish via separate portals — Napier is in the Napier + Whanganui cluster.

If you're doing Hawke's Bay property research, cyclone-resilience analysis, or agricultural land-use work — this is the source.

What's in the catalogue

Council Code Datasets Highlights
HBRC hbrc 14 Coastal erosion (66/100/150yr scenarios), liquefaction, river flood scenarios, water-management areas
Central Hawke's Bay District (CHBDC) chbdc 13 Full DP suite + post-Gabrielle cyclone-affected properties + flood scenarios
Hastings District (HDC) hdc 6 DP zones + designations

Standout datasets

  • chbdc_cyclone_affected_properties — post-Cyclone Gabrielle property impacts (Feb 2023). Critical for property + insurance research.
  • hbrc_coastal_erosion_likely_66, hbrc_coastal_erosion_likely_66, hbrc_coastal_erosion_possible_33 — multi-horizon coastal erosion scenarios
  • hbrc_chb_hdc_wdc_liquefaction_severity — liquefaction severity for Central HB + Hastings + Wairoa (combined regional product)
  • chbdc_haz_flood_full, chbdc_haz_flood_risk_areas — Central HB flood hazards
  • chbdc_haz_tsunami_inundation — tsunami inundation modelling (Pacific exposure)

Common patterns

Post-Gabrielle property impact

affected = client.hawkes_bay("chbdc_cyclone_affected_properties", as_sf=True)
# affected has impact_category column
print(affected["impact_category"].value_counts())

Multi-horizon coastal erosion

import geopandas as gpd

scenarios = {
    "66yr":  client.hawkes_bay("hbrc_coastal_erosion_likely_66", as_sf=True),
    "100yr": client.hawkes_bay("hbrc_coastal_erosion_likely_66", as_sf=True),
    "150yr": client.hawkes_bay("hbrc_coastal_erosion_possible_33", as_sf=True),
}
for label, layer in scenarios.items():
    area_km2 = layer.to_crs("EPSG:2193").area.sum() / 1e6
    print(f"{label} likely-erosion area: {area_km2:.1f} km²")

Source-specific notes

  • Cyclone Gabrielle context: Hawke's Bay was the worst-affected region in February 2023. chbdc_cyclone_affected_properties is a CHBDC-specific dataset; equivalent layers for Hastings + Napier + Wairoa exist on their own portals but aren't all in eolas yet.
  • Multi-horizon coastal-erosion modelling: HBRC publishes 66yr / 100yr / 150yr scenarios — useful for forward-looking property + insurance work. Don't conflate with NIWA's sea-level-rise projections (different methodology).
  • Hastings + Napier: Hastings publishes some data here (hdc_*) but more via its own portal. Napier is in the Napier + Whanganui cluster because of how its data is published.
  • Cross-cluster shared product: hbrc_chb_hdc_wdc_liquefaction_severity is a joint product covering Central HB + Hastings + Wairoa — useful regional view.
