Māori land

Last reviewed: 23 August 2026

Māori land information sits across whakapapa, law, governance and place. GIS can help you pull kōrero, boundaries and context into one view, but you need to be clear about what each dataset represents and what must stay restricted. This page focuses on practical sources and workflows for working with whenua Māori in a GIS context, written for iwi and hapū staff, trust managers, kaitiaki and practitioners.

What people usually need from a whenua map​

  • Find where a block is, and what surrounds it
  • Confirm the registered block name and Māori Land Court district
  • Understand management structures such as trusts, incorporations and reservations
  • Prepare maps for hui, planning, funding or on-the-whenua mahi
  • Combine whenua with taiao, hazards, infrastructure and planning layers
  • Build an internal register of whenua interests, responsibilities and contacts
  • Share useful context without exposing owners or sensitive sites

Start with the right concepts​

You will often work with two different concepts that do not always line up one to one.

Māori land block

  • A block is a Māori Land Court record concept tied to land status and Court record context.

Parcel

  • A parcel is a cadastral mapping unit used nationwide. Parcels are often the best spatial index for joining to planning, infrastructure and other property-based datasets.

Use blocks for whenua context and governance kōrero, and parcels to connect that context to other technical datasets.

Where to find Māori land record context​

Pātaka Whenua​

Pātaka Whenua is the Māori Land Court portal for searching and accessing Māori land information, including minutes and orders.

Use it when you need a confirmed block name and record context, minutes and orders behind decisions, or Court references to support governance discussions.

Māori Land Court published data​

The Māori Land Court publishes regular documents and registers, including Māori Land Update reports, Māori Land Blocks in New Zealand and the Māori Incorporation Register.

Always check the notes on the document you download because published lists can exclude some land categories and blocks under review.

Tōku Whenua reports​

Te Puni Kōkiri's Tōku Whenua information can be useful for high-level environmental and land characteristic context when scoping options.

Whenua Māori Visualisation Tool​

The Manaaki Whenua visualisation tool is useful for quick context and early kōrero. Its land block information is older, so treat it as a guide rather than a current source of record.

Where to find surrounding context layers​

Useful public sources include:

Most councils publish district-plan, hazard, infrastructure and environmental context. Search by the council name plus open data or GIS data.

Māori land boundaries in GIS​

Māori land record context is often strong, but boundaries are not always available as one single current authoritative dataset. Different organisations hold different versions, and some boundaries are indicative rather than legal.

Separate your work into two linked parts:

  • a boundary layer containing the geometry, source and date
  • a record layer containing block context, governance and use, with links back to Court records

Link them with an internal identifier you control and maintain.

Māori Land Spatial Dataset​

A widely used boundary dataset is commonly referred to as the Māori Land Spatial Dataset, MLC_2017_05. It is still served by some councils and agencies and remains useful as a practical baseline, provided its age and limitations remain visible.

A data.govt.nz request lists the original shapefile, geodatabase and fact sheet:

Common attributes​

Field names can vary by publisher. Common fields include:

MLOL_URILegacy Māori Land Online linkTreat as legacy
Shape_Area / Shape_LengthGeometry measuresTechnical QA

Treat these as supporting context fields, not legal proof.

LINZ parcels​

NZ Primary Parcels and NZ Primary Land Parcels are useful for linking whenua context to current cadastral geometry.

A Māori land block can overlap multiple parcels, and a parcel can sit within different record contexts over time. Use parcels as a spatial index, not as your only whenua definition.

Practical workflow​

To connect block context to parcel context:

  1. Load your Māori land layer.
  2. Load NZ Primary Parcels or NZ Primary Land Parcels.
  3. Run a spatial join using intersects.
  4. Export a table of parcel IDs linked to each block.
  5. Store the source of the Māori land boundary, date checked and known issues.
  6. Re-run the linkage when parcels update or a better block boundary becomes available.

Suggested internal register​

Useful fields include:

  • block_name
  • block_id
  • mlc_district
  • land_status
  • rohe
  • governance_type
  • governance_name
  • parcels_linked
  • boundary_source
  • boundary_quality
  • last_checked_date
  • sensitivity
  • tikanga_notes
  • contact_role
  • notes

Keep sensitive details out unless you have a secure system, clear permission and a defined purpose.

QGIS workflow​

For a hui-friendly whenua context map:

  1. Confirm the block record context in Pātaka Whenua.
  2. Create predictable source, working, output and metadata folders.
  3. Add imagery for context.
  4. Add parcels and only the technical layers that support the kaupapa.
  5. Add planning or hazard information only where relevant.
  6. Keep the map readable and label the boundary source and checked date.
  7. Store source, date, licensing, sensitivity and distribution notes beside the output.

Combining whenua with other datasets​

Common combinations include:

  • whenua and hazards for resilience work
  • whenua and infrastructure for servicing constraints
  • whenua and environmental data for taiao planning
  • whenua and planning rules for zoning and overlays
  • whenua and imagery for kōrero and ground checking

Keep analysis layers separate from published layers. The working model can be complex while the hui map remains simple.

Check the source before using it​

For every whenua-related layer, record:

  • source organisation or knowledge holder
  • dataset or record name
  • version, publication date or last checked date
  • what the source is authoritative for
  • what it is not authoritative for
  • whether the geometry is legal, administrative, indicative or locally maintained
  • any transformation or spatial join applied
  • sensitivity and sharing conditions

A Māori Land Court record may be the relevant legal or administrative source for a particular land-status question. A LINZ parcel is the relevant cadastral representation for parcel geometry. Neither source defines whakapapa, whenua relationships or local cultural meaning.

Use Provenance and source checking for the wider method.

Try it now​

Choose one whenua block or area you know.

  1. Confirm its block name and Māori Land Court district in Pātaka Whenua.
  2. Add your best available Māori land boundary layer to QGIS.
  3. Record the source and date of that boundary before styling it.
  4. Add current LINZ parcels and identify whether the block maps to one parcel or several.
  5. Add one useful context layer such as imagery, a road or a hazard layer.
  6. Create a small metadata note containing block_source, boundary_source, boundary_quality, parcel_source and last_checked.
  7. Produce one A4 hui map with the boundary source visible in the map notes.
  8. Remove owner-level or sensitive information from the shareable version.

The exercise is successful when another person can tell what each line on the map represents and where it came from.

Explore in Matawhenua​

Use the Matawhenua 2D and 3D viewer to orient yourself around whenua, terrain and surrounding context. When a decision depends on Māori Land Court records, cadastral geometry or another source of record, return to that original source rather than relying on the viewer alone.

Privacy and safety​

Avoid storing owner lists in GIS unless there is a secure system, clear permission and a clear purpose. Treat summary owner and share counts carefully in small communities. Keep wāhi tapu and other sensitive layers restricted, and do not publish exact locations without mandate and approval.

Common issues​

If block names differ across sources, store the source name and date rather than overwriting one with another. If boundaries are indicative, label them that way in the layer and output notes. Do not assume one block equals one parcel. Some context tools and datasets lag updates, so use Pātaka Whenua and current provider pages where a current record matters.
