Categorisation update – 28 August

Source: Auckland Council

Welcome to our fortnightly categorisation programme update.

Final property categories have been provided to 2175 homes, with 725 classed as Category 3 and eligible for a buy-out (as of 28 August). This has been supported by a huge effort by our technical and engineering teams having completed over 3100 desktop assessments and 2050 site assessments. 

500 Category 3 homeowners had received or accepted a buy-out offer, and 217 properties had completed their sale and purchase agreements (as of 23 August).

Overall, 3129 property owners have now registered for the categorisation scheme out of 7389 known impacted properties (as of 28 August). There is still time for at risk homeowners to sign up to the limited scheme. While the deadline for registering is 30 September, we strongly recommend doing this as soon as possible. See our story Registering for a Risk Category for more information. 

In some locations we have not been able to finalise risk reports and categories until decisions about local infrastructure solutions have been made. 

Muriwai and Māngere stormwater solutions

We are pleased to have received the Government’s approval of its co-funding for our first three infrastructure resilience solutions in Muriwai around Domain Crescent and in Māngere’s Te Ararata and Harania catchments. Community information meetings have been held in Māngere East and Māngere Central, and we are waiting to hear back on approval of the Order In Council which will allow the project to be delivered as soon as possible. For more information on these projects email bluegreen@aucklandcouncil.govt.nz. 

Categorisation progresses in other infrastructure areas

In other areas, the necessary community infrastructure projects are more complex and could take many years to design, fund, plan, consent and construct. So an amendment to the Auckland recovery co-funding agreement has been approved by the Government which allows Council to offer buy-outs for high-risk properties where an infrastructure solution can’t be delivered in a reasonable timeframe. Council is now progressing risk reports for properties in these project areas, including neighbourhoods around Nile Road in Milford and Clover Drive in Henderson.

See Our Auckland to learn more about flooding assessments and landslide assessments.

An ongoing note on the complexity of categorisation

Many properties have proven more complex to categorise for several reasons:

• There is an intolerable risk to life, but we need to assess the feasibility of a mitigation at the property. Examples include retaining walls, house raising or moving, altering fences and other structures blocking overland flow paths, or changes to driveways or landscaping
• There is an intolerable risk to life, but we have been waiting on confirmation of a community infrastructure project that could reduce this risk for whole neighbourhoods. Examples include redirecting overland flow paths, making more space for water to flow and pool, stopbanks, and upgrading culverts and roads. These projects are being scoped looking at feasibility of timelines, practicality, costs and impacts
• There are both flooding and landslip issues at the property
• Recent work at neighbouring properties, or the shifting of land, have changed the risk profile since we started.

See key categorisation and buyout figures below.

Note: Not every home will need a site assessment, but some may need more than one

Categories confirmed (at 28 August 2024)

*​A small number of properties that have registered for the programme are ineligible, including those with vacant land, commercial/non-residential properties, or properties owned by public service providers. The programme is focused on addressing risk to life in residential situations.
