A 20m resolution digital elevation model of the bathymetry of the Hauraki Gulf as a ESRI binary grid. Data was compiled from NIWA and Land Information New Zealand bathymetric and hydrographic surveys.

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.

NIWA (and its predecessor, the New Zealand Oceanographic Institute (NZOI)) publishes series of charts and posters of coastal bathymetry, sediment, and other information of the marine environment. Further information about the charts can be found at http://www.niwa.co.nz/publications/charts. The following is a description of the series of charts that have been published: Coastal bathymetry / sediments, 1:200,000 NIWA produces a variety of Bathymetric Charts that cover coastal New Zealand and many offshore areas. Bathymetric charts show the depth of the ocean contoured into lines of equal depth (bathymetry) and are particularly useful for pinpointing pinnacles, holes, and other bottom features. A sediment edition that illustrates the nature of the bottom type (rock, sand, gravel, and so on) is available for some of these same areas. Please order your charts by name (e.g. Cook Strait Bathymetry, or Bay of Plenty Sediment). Oceanic bathymetry / sediments, 1:1,000,000 NIWA produces a series of oceanic charts at this smaller scale. These illustrate the large scale features of the New Zealand region, particularly those offshore in deeper water. Some areas also have a sediment edition. Please order your chart by name (e.g. Three Kings Oceanic Bathymetry). Lake Bathymetry, various scales NIWA has published a lake chart for every lake in New Zealand that can be surveyed, except for Lake Dunstan. The charts are of various scales that are determined to be the most appropriate for the size of the lake. The compilation and publication dates range from 1966 to 1989. Miscellaneous charts Other charts include a range of bathymetric charts of areas of special interest around New Zealand. These include many of the Sounds of Fiordland, New Zealand Island Territories, and the Marlborough Sounds. We also produce a range of sediment charts, such as Manukau and Waitemata Harbours, Rangaunu Harbour, and Wellington South Coast. Some excellent charts of various scales are also available that show the entire New Zealand region. There are more than 70 charts in this miscellaneous series.

Bathymetric contour data set 50m - 12,000m around the New Zealand region.
-
This dataset provides the most up-to-date bathymetry of one of the largest areas of deep-water seabed under national jurisdiction. The 250m resolution gridded bathymetric data set encompasses New Zealand's Exclusive Economic Zone and is available in multiple high-resolution file formats to suit a range of imagery and mapping needs.

Bathymetry vector contour dataset. Compilation of data digitised from published coastal charts, digital soundings archive, navy collector sheets and digital multibeam data. Contour interval 50m in depths greater than 200m and 10m in depths less than 200m (where available). In areas without high resolution data the regional bathymetry data was used to fill gaps.
