A group of Auckland homeowners is contesting new “very high hazard” flood classifications recorded on their Land Information Memorandum (LIM) reports, raising questions for insurers and brokers about how council hazard data is interpreted in underwriting and disclosure.
On a street in Bayview on Auckland’s North Shore, homeowners recently learned that their properties are now mapped in a “very high hazard” floodplain adjacent to a bush reserve and stream. Some residents say the stream has not overtopped in the three decades they have lived there, including during the 2023 Auckland Anniversary storm, and want to understand the technical basis for the shift in status.
One owner, Marty Jaynes, said neighbours met to unpack the possible effects of the new label on their property interests and insurance. “They’re worried about the implications now that this risk is on the LIM, that insurance premiums could go up, that there will be extra hoops to jump through if they want to do anything to their homes. It was quite a shock; they [Auckland Council] did say this is the worst-case scenario, but that’s not what people see when they read a LIM,” Jaynes said, as reported by Stuff.
The group asked Auckland Council for an on-site visit, a review of the hazard category, and details of the modelling approach and inputs. Jaynes said the written reply did not respond to those specific points. Neighbour Bjoern Pauly called the reply a “blanket response” and “not very helpful at all.” With a young family and plans to extend his home, he said the new hazard notation “gives a lot of uncertainty, and a bundle of nervousness about insurance.”
Auckland Council’s stormwater unit, Healthy Waters, has said it is not required to individually notify property owners when hazard mapping is updated, but it must ensure information is publicly available. Council material describes the online flood layers as indicative, developed from regional and catchment modelling and subject to confirmation at site level. Pauly questioned why no officer had inspected the properties and why owners were not directly informed when the “very high hazard” layer was applied. “You would think, if you are living now in a high hazard zone, that someone should say, ‘look, this is what you need to do.’ What does it mean? Do you have to evacuate in advance? It feels like a red sticker has been placed on my house,” Pauly told Stuff.
Andrew Chin, Auckland Council’s head of strategic initiatives at Healthy Waters, said the flood maps on the council’s Flood Viewer, GeoMaps, and LIMs are prepared for regional and catchment planning purposes. “They are not created at a site-specific level. It is not the council’s role to obtain site-specific flood hazard information for private properties in Auckland – and it’s not realistic for us to do so, either. What we want property owners and future property owners to understand is the role of the flood maps on Flood Viewer, GeoMaps, and LIM reports,” Chin said.
Chin said the maps are intended to indicate where more detailed work may be needed. “The maps can be considered alongside other information such as site-specific reports, which are likely to provide more detail about the nature and extent of any hazard. While we understand the frustration of dealing with potential future risks in the present, like all councils across the country, flood information on our LIMs must include the impact of climate change on the potential hazards that it identifies. It’s important to remember that the information is used not just by current property owners, but prospective homeowners and residents, too,” Chin said. After media enquiries, Chin confirmed his team would set up a meeting with the Bayview residents.
The Bayview dispute illustrates the growing role of council records in shaping how natural hazard risk is perceived by owners, lenders, and insurers. Auckland Council guidance explains that a property file generally contains consent documentation and correspondence and “does not replace a LIM report.” It may not record unconsented building work, and not all historical regional consents have been digitised. A LIM is described as a consolidated summary of information the council holds about a property. That may include natural hazard information such as flooding, erosion, subsidence or slippage, drainage infrastructure, rates data, consents, any relevant notices or orders, and placards from post‑event rapid building assessments. The increasing amount of structured hazard information on LIMs expands the data available at new business, renewal, and claims. It also strengthens the link between council mapping and what a reasonable insured might be expected to know when answering risk questions or updating material facts.
The Bayview situation is unfolding as updated national direction on natural hazards and highly productive land comes into force under the Resource Management Act (RMA), affecting how councils across New Zealand identify and manage risk in plans and consent decisions. RMA Reform Minister Chris Bishop said: “These changes will make it easier to enable the development that New Zealand needs while still protecting our most productive land and helping communities become more resilient to natural hazards.” He said the National Policy Statement for Highly Productive Land has been amended to allow a more flexible approach to Land Use Capability Class 3 land, while continuing to protect Classes 1, 2, and 3, with “a more enabling pathway for urban development on LUC 3 land.”
Bishop added: “I’m also pleased that a new National Policy Statement for Natural Hazards is being introduced. New Zealand is particularly vulnerable to natural hazards, many of which are being intensified by climate change. Our changes today set a consistent, risk‑based approach for how councils manage natural hazard risks, such as flooding, storms, and erosion, when planning new developments. This ensures councils take a proportionate and consistent approach, so communities are safer and more resilient.” He said measures such as the National Adaptation Framework, New Zealand’s Flood Map, and the new planning system are intended to offer “clear, up-to-date information about natural hazard risks for their properties” and require councils to provide “easy-to-understand hazard information in LIMs, including details like report age and scope.”
Minister of Local Government Simon Watts said a forthcoming national flood map will integrate multiple data sources. “It will provide a trusted source of flood risk information for the whole country. We are working towards having the first generation of the map ready within the next year. Currently, New Zealand doesn’t have a single view of the data. This flood map is the first step. Over time we expect the quality, consistency, and coverage of the data will continue to improve,” Watts said.
A nationally consistent flood dataset, used alongside council‑level LIM disclosures and any property-specific technical reports, is likely to inform model development, portfolio accumulation analysis and product design. The Bayview case, and similar disputes in centres such as Tauranga, suggests more direct interaction between homeowners, councils, and insurers over how hazard classifications are derived, how they should be interpreted, and how they flow through to pricing, terms, and the long‑term availability of cover.
