Finding and accessing MGI

Finding and accessing data facilitates its reuse.

In New Zealand, MGI is collected by various public and private organisations. The NZMGI-WG aims to increase the findability and accessibility of MGI.

National MGI Inventory

The NZ National MGI inventory was created to improve understanding of what data was collected in New Zealand waters and facilitate its discovery. 

Initial work to create the NZ National MGI Inventory started through the Open Data programme with detailed stocktakes created by six organisations. Results of this work are available through catalogue.data.govt.nz

Those stocktakes were simplified, in order to consolidate them into one National MGI inventory and facilitate contribution from other organisations. Data has been grouped by categories and types, regions and organisations. Information on where to access or how to request data is also included.

The National MGI Inventory is now discoverable and accessible via a web app:
NZ Marine Geospatial Inventory app

NZ marine data owners are encouraged to contribute to the National MGI Inventory by taking a short survey.

Support in undertaking a detailed Marine Geospatial Stocktake is available, though a guidance document published by the NZ MGI WG:

Enabling Integrated Marine Management – an innovation project

In 2021 Toitū Te Whenua LINZ partnered with the following agencies to successfully secure funding through Department of Internal Affairs Digital Government Partnership Innovation fund:

  • Office for Māori Crown Relations | Te Arawhiti
  • Department of Conservation | Te Papa Atawhai
  • Ministry for Primary Industries | Manatū Ahu Matua

This partnership explored how marine geospatial data can enable integrated marine management.

The Enabling Integrated Marine Management Project has two core components:

  • A technology Proof-Of-Concept (POC)test the value of a cloud-based Datamesh infrastructure in connecting existing data platforms, tools, and systems from various agencies.
    Read the findings and recommendations from this POC
  • Te ao Māori perspectiveengage with Kaitiaki o te Moana to facilitate access and reuse of MGI by Kaitiaki o te Moana. Outcomes of this component include:
    • a hui in April 2023
    • an online huitopa in June 2023
    • a wananga report which summarises insights, key messages and recommendations (available upon request at hydro@linz.govt.nz)
    • establishment of a kāhui kaumatua/advisory group to progress work items that support Māori in discovering, accessing and reusing MGI. 

MGI Portals

The NZ MGI Data Portal study was undertaken to:

  1. support data users in finding, accessing and reusing NZ MGI
  2. encourage data custodians to share the MGI they hold
