Category 2C homes in Māngere

Homes across Auckland that were impacted by the 2023 storms are being assessed for their future flood and landslide risk.

Based on the government's risk categories framework, the assessments are focused on identifying where there is an 'intolerable risk to life' from future flooding or landslides, and whether anything can be done to reduce that risk. Any support aims to help address the risk, or where that's not possible - to help whānau move out of harm's way.

About Category 2C

A 'Category 2C' is given to homes that meet the threshold of intolerable risk to life, but where Auckland Council is planning a community stormwater project that will reduce the risk to an acceptable level.

Māngere is the first community to receive priority funding for flood resilience projects, which includes $53 million for the rapid delivery of stormwater projects at Harania Creekand Te Ararata Creekin Māngere. The projects are expected to start in the first few months of 2025 and be completed by mid-2026.

Not all homes in these areas will be assigned a Category 2C - each home's category depends on the unique level of risk and whether these projects or a construction solution at the home can reduce that risk. This is why confirming categories in the two project areas takes more care. 3Properties given a Category 2C will have their risk reduced to a reasonable level when the project in their neighbourhood is complete in mid-2026.

Category 2C Homeowners Guide

Preparing your home, tenants and whānau

The risk assessments we carry out are based on an extreme event with a one per cent chance of happening or being exceeded in any year. While they are uncommon, it is very hard to predict if, or when, another large storm may happen again.

So until the projects are complete it's especially important you take steps at home to reduce your flood risk, while having an emergency planin place in case another major storm hits.

We expect homeowners to have open communication with their tenants about the property category and any risks, as well as ensuring they have information about emergency preparedness.

More information about preparing for flooding is available in the Category 2C Homeowners Guide and via the link below.

Category 2C FAQs

What support am I eligible for as a 2C homeowner?

Your property has been confirmed as Category 2C because an upcoming stormwater project in your neighbourhood will reduce the future risk to life at your home to a safe level. This means you will be able to continue living in your community and will not need to carry out construction solutions to reduce the risk at your home. Because of this you won't have access to buy-out or construction grant support. However, you will continue to have access to our Storm Recovery Navigator Service connecting you to wellbeing, financial and accommodation support where relevant. If you don't have a navigator and would like one, please email [email protected].

What if I have more questions or disagree with my category?

If you have questions about your report and how your category was assigned, we have a technical expert that can meet with you to discuss your questions. You can continue using this technical helpdesk service for any other questions about your report.

If you still disagree with your Category 2C, you can raise a dispute through the formal dispute process. You'll also have the option to seek a further external review if you are unhappy with that decision.

Outside of technical helpdesk support, your Navigator will continue doing their best to support your wider wellbeing needs and can help you navigate these next steps.

What about the risk levels while the projects are underway?

Local stormwater systems are built to international standards, to manage a good amount of rainfall. The categorisation risk assessments we carry out are based on an extreme event with a one per cent chance of this happening or being exceeded in any year. While they are uncommon, it is very hard to predict if, or when, another large storm may happen again.

A local stormwater project will reduce the risk to life at Category 2C homes, but the full risk reduction benefits will only be realised when the project is fully completed in mid-2026.

So, while Auckland Council is working on this major project, it is also prioritising stormwater monitoring, maintenance and catchpits in your neighbourhood.

At home, there are also important things you can do to reduce your flooding risk and prepare in case one of these extreme storms happens again. We have provided some general information in our 2C homeowner guide about preparing for major storms, and a community-level plan is being finalised for each local board area.

What if I have tenants?

We expect homeowners to have open communication with their tenants about the property category and any risks, as well as ensuring they have information about emergency preparedness. More information about preparing for flooding is available in the Category 2C Homeowners Guide or via the links above.

Will my Category 2C home still be insurable?

We have been working closely with the insurance industry since the floods. They have told us that 2C homeowners will still be able to get insurance cover, but ultimately this is up to individual insurance companies.

Auckland Council has to disclose property categories to the insurance industry because they use official information requests to ask for this information. This means your insurance company will know what your property category is. We recommend you speak to your own insurer to understand if there is an impact on your insurance policy.

If your insurer makes a decision to stop providing flood cover, or they increase your premiums, we recommend you speak to other insurance companies as you may find another company will provide a better policy for you.

What are the stormwater projects in Māngere?

Māngere is the first community to receive priority funding for flood resilience projects which includes $53 million for the rapid delivery of flood resilience projects at Harania Creek and Te Ararata Creek in Māngere. The projects are expected to start in the first few months of 2025 and be completed by mid-2026.

For more information on each project visit:

• Harania Creek project

• Te Ararata Stream project

Information about key impacts is available on the project webpages and you can contact the project team at [email protected]

How does Auckland Council measure 'intolerable risk to life' from flooding risk?

For flooding, an intolerable risk to life is where there is a high risk to life for vulnerable people in a flood event that has a one per cent chance of happening or being exceeded in any one year (an existing 1% Annual Exceedance Probability (AEP) flood event).

To determine the risk to life from floods on a property, Auckland Council completes a 'flood danger risk assessment' and assigns a 'danger rating' that indicates the threat to people's lives from flooding inside or outside the home.

More information is available in the Category 3 Homeowners Guide or on our guide to flood risk assessments.

What are the risk categories?

Category 1	These properties do not meet the threshold for intolerable risk to life. They are not eligible for a buy-out or other financial support from the council but can access wellbeing and other support.
Category 2P	Category 2P means there is intolerable risk to life at the property, but changes to the property can be made to reduce the risk to life from future weather events. Homeowners can apply for a grant to make these changes so that the property is safe to live in.
Category 2C	Category 2C means that there is intolerable risk to life at the property, but community-level measures (or interventions) will be developed to reduce the risk to life at a property.
Category 3	Category 3 means there is intolerable risk to life at the property, and changes to the property are not feasible. Category 3 properties can opt-in to the voluntary buyout by the council.
