This page is to document what basins have been modelled throughout NZ and the type of the model

TypeClassification
1Based on geological maps and DEMs
2

Refined based on additonal data

  • Boreholes
  • Geophysical Testing
    • HVSR
    • Surface Wave testing
    • P-wave refraction
3Further development of type 2
4Extensive datasets with advanced modelling

Model is currently implemented, but we need to update Port Chalmers. "Offshore" Inlets need to be modeled as a part of the basin going forward.

Currently implemented as two separate basins (Mosgiel / Balclutha) but is joined by sedimentary rock.

Motu Bay done - USER2022

Waiapu Bay done - USER2022

  • Include all of the costal river valleys on the East Cape (e.g., Waiapu River, Hicks Bay, Waihau Bay, Motu River)

Motu River

  • Stop at Moto River, working around the East Cape from Gisborne. Haurere Point should be included in Whakatane




Whakatane, Edgecumbe, and Murupara
USER 2020 - NI - Partially done

  • Start with existing USER Whakatane Basin
  • Exclude Tauranga and lakes near Rotorua


2.07+William Lee21p12Wairarapa1USER2021 - Integrated

  • Southeast North Island including Masterton and Martinborough
  • Consider adding east costal basins (e.g., Uruti Point)

Northern Hawkes Bay — Heretaunga Plains to Mahia


USER2021 - integrated


The areas marked with black X's were either considered too shallow or sedimentary rock so weren't modelled as a basin.

2.07+William Lee

Southern Hawkes Bay — Central Hawkes Bay and Tararua Districts


Looks like there are a couple more along the east coast to be done too

  • Long Valley running from the Ngaruroro River to Eketahuna. 
  • Include any small basins south of Hastings and along the coast.
  • Note: Will be near the Wairarapa and Manawatu-Whanganui / Taranaki basins, but does not physically touch due to rock.
  • Physically connects to Northern Hawkes Bay in the Ngaruroro River valley
    • Need to check consistency in the bedrock surfaces at the intersection.





Rotorua and neighboring lakes

  • Sedimentary basins surrounding the lakes, could be complex with interaction from extrusive volcanic rocks (basalt, tuff, pumice).
  • Exclude Whakatane, Tauranga, and Hauraki Plains



Manawatu-Whanganui / Taranaki

  • Large basin, including: Paraparaumu, Kapiti Coast, Palmerston North, Whanganui, New Plymouth
  • Sediments and shallow volcanic lahars near Taranaki
  • Start with outlining the basin and any outcrops
