Bay of Plenty Councils data via eolas

The Bay of Plenty region covers ~350,000 people across Bay of Plenty Regional Council (BoPRC, "Toi Moana") and five territorial authorities — Kawerau, Ōpōtiki, Rotorua-Lakes, Tauranga, and Western Bay of Plenty. eolas serves 46 datasets spanning the region — with particularly strong tsunami + volcanic hazard data reflecting Bay of Plenty's geophysical setting.

If you're doing Bay of Plenty planning, hazard, or coastal-management work — this is the source.

What's in the catalogue

BoPRC — 10 datasets

Theme Datasets
Tsunami boprc_tsunami_evacuation_2025, boprc_tsunami_inundation_2500yr
Hazards boprc_historic_flood_extents, boprc_liquefaction_level_b
Regional Coastal Environment Plan (RCEP) boprc_rcep_ascv (areas of significant cultural value), boprc_rcep_coastal_environment_zone, boprc_rcep_historic_heritage_coastal, boprc_rcep_ibda_a, boprc_rcep_ibda_b, boprc_rcep_onfl (outstanding natural features + landscapes)

Tauranga City Council (TCC) — 14 datasets

The region's largest urban centre + the country's busiest port. Coverage spans district plan zones, designations, hazards (coastal, flood, liquefaction), heritage, and infrastructure.

Western Bay of Plenty (WBOPDC) — 8 datasets

District plan zones + hazards covering the urban-rural fringe around Tauranga.

Rotorua-Lakes (WKDC pattern, 6 datasets), Ōpōtiki (5), Kawerau (3)

Smaller TAs — district plan zones, heritage sites, basic hazard layers.

Refresh schedule

Weekly, Wednesday morning NZ time. Most BoP councils publish via ArcGIS portals; BoPRC uses data.boprc.govt.nz.

meta = client.info("boprc_tsunami_evacuation_2025")

Common patterns

Tsunami evacuation zone lookup (BoPRC scenario)

import geopandas as gpd
from shapely.geometry import Point

pt = gpd.GeoSeries([Point(176.1651, -37.6878)], crs="EPSG:4326")  # central Tauranga
evac = client.bay_of_plenty("boprc_tsunami_evacuation_2025", as_sf=True)
zone = gpd.sjoin(pt.to_frame("g").set_geometry("g"), evac, predicate="within")
print("Tsunami evacuation zone:", zone["zone_name"].iloc[0] if len(zone) else "none")

Coastal protection overlay

coastal = client.bay_of_plenty("boprc_rcep_coastal_environment_zone", as_sf=True)
historic = client.bay_of_plenty("boprc_rcep_historic_heritage_coastal", as_sf=True)
# Combined coastal protection footprint
import pandas as pd
combined = pd.concat([coastal, historic])
print(f"Coastal protection area: {combined.to_crs('EPSG:2193').area.sum() / 1e6:.0f} km²")

Source-specific notes

  • BoP has high geophysical hazard: White Island / Whakaari, Mt Tarawera, Rotorua geothermal systems, Hikurangi subduction interface — tsunami + volcanic + earthquake hazards are real and well-modelled.
  • Tauranga has separate publishing: TCC's data is on its own portal; some layers overlap with BoPRC's regional layers. For property-level planning, use TCC's; for regional-scale risk, use BoPRC's.
  • Ōpōtiki tsunami: opotiki_coastal_hazard_ohiwa covers the Ōhiwa Harbour — particularly exposed to tsunami; check before coastal investment decisions.
  • RCEP coverage: the BoP Regional Coastal Environment Plan layers are statutory + binding on coastal subdivision / development. Use these (not BoPRC's general planning data) when assessing coastal-zone constraints.
  • Rotorua geothermal: the geothermal field underlying Rotorua city has specific consenting rules (sourced via Rotorua Lakes Council); not all geothermal-protection layers are yet in eolas.
