[The Place Names Gazetteer](http://www.linz.govt.nz/placenames/find-names/nz-gazetteer-official-names/nzgb-gazetteer) contains **official** and **unofficial** place names under the jurisdiction of the New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB). Official place names are those that have been assigned, altered, adopted, approved, and validated under the NZGB Act 2008 or through other statutes that assign official names, for example, Treaty settlement legislation. Unofficial place names are those that have not been processed under the NZGB Act 2008 or through other relevant statutes. Data is extracted from Land Information New Zealand’s (LINZ) ‘New Zealand Gazetteer of Official Geographic Names’, which is maintained by the NZGB Secretariat. Geographical coverage encompasses New Zealand, the Ross Dependency of Antarctica, and the Continental Shelf of New Zealand. The NZGB has naming jurisdiction over: - natural features such as mountains, peaks, valleys, glens, forests, lagoons, swamps, creeks, streams, rivers, fords, lakes, glaciers or ice features, bays, islands or harbours (including man-made features of the same type) - railways or railway stations, but not railway features such as marshalling yards, transfer sites, or track point locations - places, i.e. cities, towns, villages, sites, areas, or similar places, including suburbs and localities - undersea features - Crown protected areas - Districts and regions (altering only if requested by the local authority) Each name is provided with a location represented by a point. More complex geometry (e.g lines for rivers or areas for suburbs) is not currently available. Each geographic feature has one or more place names associated with it. Place names usually comprise two components – ‘specific’, being for the proper noun, and ‘generic’, being a description of the geographic feature type. Information provided for each place name may include: name; name status (whether official or unofficial); geographic feature type; authority by which an official name became official; district within which the name is located; geographic location; reference information; history/origin/meaning; and additional notes. Not all information is available for all names. Positional accuracy is generally the same as 1:50K mapping. Information accuracy reflects information at the time of original capture.

URQIS accesses a database of urban runoff quality data collected from urban areas in the North Island and South Island, with the extent of coverage between Whangarei and Invercargill, New Zealand. The data are compiled by NIWA and start in 1990. The following water quality parameters are included in the database: Total Suspended Solids (TSS), Volatile Suspended Solids (VSS), Suspended Solids Concentration (SSC), Water Temperature, pH, Conductivity, Dissolved oxygen saturation,Dissolved oxygen concentration, Turbidity,Black disc, Total Zinc, Dissolved Zinc, Particulate Zinc, Total Copper, Dissolved Copper, Particulate Copper, Total Lead, Dissolved Lead, Particulate Lead, Total Aluminum, Dissolved Aluminum, Total Antimony, Dissolved Antimony, Dissolved Arsenic, Total Arsenic, Dissolved Cadmium, Total Cadmium, Dissolved Chromium, Total Chromium, Dissolved Iron, Total Iron, Dissolved Manganese, Total Manganese, Dissolved Mercury, Total Mercury, Dissolved Nickel, Total Nickel, Dissolved Silver, Total Silver, Dissolved Magnesium ,Total Magnesium, Dissolved Potassium, Total Potassium, Dissolved Sodium, Total Sodium, carbonaceous BOD5, Chemical oxygen demand, Oil and Grease, Hardness (as CaCO3), Alkalinity, Sulfate, Chloride, Fluoride, Enterococci, Escherichia coli, Faecal coliforms, Total nitrogen, Nitrite-N, Nitrate-N, Nitrate+nitrite-N (NOxN), Ammoniacal-N, Dissolved inorganic nitrogen, Total dissolved nitrogen, Total Kjeldahl nitrogen, Dissolved Kjeldahl nitrogen, Total phosphorus, Total dissolved phosphorus, Dissolved reactive phosphorus.

The snow melt estimates were generated through the separation of daily precipitation into rainfall and snowfall components to provide 1981-2010 mean annual snowfall and rainfall maps. The ratio of the catchment-based accumulation of these precipitation components was then found for each river reach in the New Zealand River Environment Classification (REC), which is equivalent to the ratio of snow and ice melt to flow. The REC user guide is available at: http://www.mfe.govt.nz/environmental-reporting/about/tools-guidelines/classifications/freshwater/rec-user-guide-2010.pdf Kerr, T. 2013: The contribution of snowmelt to the rivers of the South Island, New Zealand.

The seamount catalogue presents a synopsis of the physical characteristics of seamounts within the “New Zealand region” (taken here as the area bounded by 24°S, 167°W, 57°S, and 157°E). Data are collated on features with a vertical elevation of 250m or greater (thus, the term seamount is used here for discrete bathymetric features with ≥250 m of relief) with some features of 100 m or greater that are significant for the fishing industry being also included, but have presented these data in a way that accounts for differing interpretations of the terminology for undersea features of various sizes. The catalogue is maintained as a MS Excel spreadsheet.

National indicator data for river condition in New Zealand - collected by Regional Councils and the National Institute of Water and Atmospheric Research (NIWA), collated and processed by NIWA and protected by copyright owned by the Ministry for the Environment on behalf of the Crown. The dataset consists of physical-chemical water quality and macro-invertebrate data from the regional council State of Environment (SoE) and National River Water Quality Network (NRWQN) programmes. The physical-chemical water quality variables are water clarity (CLAR), Escherichia coli concentration (ECOLI), nitrate-nitrogen concentration (NO3N[1]), ammoniacal nitrogen concentration (NH4N), total nitrogen concentration (TN), dissolved reactive phosphorus concentration (DRP), total phosphorus concentration (TP), temperature (TEMP), dissolved oxygen concentration (DO[2]) and percent saturation (DOSAT), suspended sediment (SS), and turbidity (TURB). The invertebrate variables are taxa lists and counts or coded-abundance classes for each taxon. The raw invertebrate data were post-processed to generate four variables: total number of taxa in a sample (TAXA), the number of taxa from the insect orders Ephemeroptera, Plecoptera and Trichoptera (EPTtaxa), the percentage of individuals in a sample from EPT taxa (%EPTabund), and the Semi-Quantitative Macroinvertebrate Community Index for hard-bottom streams (SQMCI-hb). REC reach numbers where added to site information based on best guesses. In the dataset used for the 2012 study, the start dates for all monitoring site records were 1 January 2006 or earlier, and the end dates ranged from June 2009 to February 2012. The range of end dates poses some potential problems due to temporal variation in water quality. Further, we carried out temporal trend analyses in the current study and recent data were needed to ensure that the analyses corresponded to recent conditions. For these reasons we requested updated physical-chemical water quality data from five regional councils, to fill the most severe gaps in recent data. Each of the five regional councils provided updates, and the ending dates in the current dataset range from January 2011 to December 2012. Note that start and end dates can vary among sites within councils, and among variables within sites. Larned, S.T.; Unwin, M.J. (2012).

This dataset contains the underway data collected during the Tangaroa Voyage TAN0003 in 2000. This voyage carried out marine science studies off the Antarctic coast between the Dibble ice tongue and Ninnis Glacier as part of an experiment to study the effect of the Mertz Polynya on Antarctic bottom water formation. The voyage departed on 12th February 2000 from and returned on the 24th March 2000 to Wellington, NZ. Data include: latitude, longitude, date, time, ship heading, pitch, roll, relative humidity, air temperature, salinity, sea temperature, wind direction, and wind speed.
