The National Environmental Data Centre (NEDC) online directory http://nedc.nz is a website resource that provides information on environmental datasets for Aotearoa New Zealand and in some places wider coverage. The datasets are each hosted by one of New Zealand's Crown Research Institutes; AgResearch, ESR, GNS Science, Manaaki Whenua Landcare Research, NIWA, Scion and Plant & Food Research. The datasets are categorised in terms of Atmosphere, Biodiversity, Climate, Freshwater, Geology, Land and Ocean themes.

We present an excel spreadsheet tool called TaupōInflate and its user documentation. TaupōInflate is an easy-to-use and freely available tool to calculate and plot ground deformation from magmatic inflation at depth beneath Taupō caldera. It can be used to assess potential sources of inflation associated with unrest events at Lake Taupō. It can also be used as an educational resource for exploring general questions such as the likelihood of detecting inflating magma bodies beneath the lake.

The QualityRankings table records the quality of each source dataset or reference. Where multiple references are given in the feature classes, the ranking of the highest overall quality record is assigned to the dataset. For example, if a previously-mapped dataset was updated by the Version 1.0 NZ Landslide Dam Database authors using more recent satellite imagery or terrain models, then the metadata record for the updated mapping is linked to the landslide DamSite points via the Metadata ID field. In Version 1.0 of the database, this table contains attributes that are specific to the quality of the whole source dataset, not individual landslide dams. This might be improved in future versions of the database.

For use in several inputs to the 2022 update to the New Zealand National Seismic Hazard Model (NZ NSHM 2022), we develop an augmented New Zealand earthquake catalogue in which we import higher-quality earthquake depths and depth uncertainties, focal mechanisms, and some locations and magnitudes from several relocated and global catalogues. These are imported into and combined with the Christophersen et al. (2022) NSHM earthquake catalogue (link further down in Other resources), in which the local magnitudes that comprise most of the GeoNet catalogue were brought into alignment with moment magnitude in a way that ensures consistency through time. Next, we use event depths, focal mechanisms, 3D models of the Hikurangi and Puysegur subduction interfaces, and relative plate motion directions to classify earthquakes as upper-plate, interface or intraslab, with special treatment of the remaining lower-quality event depths in the augmented catalogue.

New Zealand Tsunami Database includes information about tsunamis that have reached the coastline of New Zealand since humans arrived in this land until the present day. The database is primarily the work of historical seismologist Gaye Downes working for GNS Science who collected reports of tsunamis around New Zealand and, in many cases, carried out research to determine parameters of the source, travel time and impact associated with each event. Reports of tsunamis that make up the core of this database come from tide gauges, newspaper articles, harbour masters, records from ships, personal diary entries and Māori oral records. This primary source material is summarised in the database and complete transcriptions are held by the database custodian. DOI: https://doi.org/10.21420/D6W9-0G74 Cite as: GNS Science. (2020).

Boxes of core, possibly chips, petroleum petrographic sections, and rock samples stored in the basement of Avalon, NIC, Wairakei, and Dunedin. It includes core materials from programmes going back to the 60s to present.

We present structural data and a 3D map of a parallel fault array from Crawford Knob in the Southern Alps, New Zealand. The data were collected in the field in 2014 and 2018 and combine structural geology field measurements with UAV (drone) and RTK (GPS) mapping. Cite as: Ellis SM, Hill MP, Little TA. 2023.

This table provides the relationships between building outlines within mainland New Zealand when buildings are split or merged. A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline. **Data vintage** This dataset does not include building outline geometry, but provides the linkages between building_id's from different aerial imagery sources in the [NZ Building Outlines (All Sources)](https://data.linz.govt.nz/layer/101292) dataset when building outlines change from single outlines split into multiple outlines, and from multiple outlines merged as single outlines. This dataset will be updated with changes in building_id relationships as new aerial imagery becomes available. Please refer to the [NZ Building Outlines Data Dictionary](https://nz-buildings.readthedocs.io/en/latest/introduction.html) for detailed metadata and information about this dataset. **Related building outlines data** [NZ Building Outlines (All Sources)](https://data.linz.govt.nz/layer/101292) - directly related to this dataset, it contains all combinations of building outlines from multiple years of imagery that have existed since the beginning of this dataset. [NZ Building Outlines](https://data.linz.govt.nz/layer/101290) - provides current building outlines only derived from the latest LINZ aerial imagery.
