Parliament has passed major changes to New Zealand's earthquake-prone building system. Northland is directly affected because the region sits within the upper North Island low seismic zone. Official guidance says the zone change will take effect after Royal Assent, while the wider risk-based system will commence on 1 July 2027. For owners, the reform is important, but it is not a reason to cancel work or ignore an existing notice without checking the current legal and project position first. [1][2][3]
What Parliament changed
The reform moves the earthquake-prone building system away from one nationwide approach and towards a system based more closely on seismic zone, building type and life-safety risk. MBIE says updated seismic zones will take effect after Royal Assent. The main new system is scheduled to commence on 1 July 2027. [1][2]
From that wider commencement date, only qualifying buildings in medium and high seismic zones will be capable of being designated earthquake-prone. MBIE identifies the main building types as unreinforced masonry buildings and buildings made from heavy materials, such as concrete, that are three storeys or taller. The legislation also introduces different levels of remediation depending on the building and its setting. [1][3]
The key Northland point is regional: the statutory earthquake-prone building system is set to stop applying in the upper North Island low seismic zone. That does not amount to a general statement that every building is structurally sound.
Why Northland is directly affected
The parliamentary commentary and MBIE guidance identify Northland as part of the low seismic zone that will sit outside the future EPB system. Once the regional change is legally in force, existing earthquake-prone building designations in that zone are to be removed and new EPB designations will no longer be made under that system. [1][3]
This matters most to owners of older commercial, community and mixed-use buildings that currently carry an EPB notice, appear on the register or have strengthening work under consideration. It may alter the statutory reason for a project, the timing of decisions and the records an owner needs to obtain. It does not automatically settle contractual, insurance, finance, lease or asset-condition questions.
Do not treat a headline as a project instruction
At the date of this article, Building Performance said the seismic-zone changes would follow Royal Assent and that more information, including an address-searchable map, would be published. Owners should check the current official status and their council record before relying on a designation being removed. [1]
If strengthening, investigation or design work is already under contract, pause before changing scope. Confirm what the engagement covers, what has been completed, what information remains useful and whether any cancellation or variation provisions apply. A removed EPB designation does not erase invoices, consultant appointments, procurement commitments or a landlord's obligations to tenants.
Low seismic risk is not zero risk
Engineering New Zealand supports a more targeted system in principle but has cautioned that a low seismic zone does not mean no seismic risk. It also notes that the detailed methodology supporting the new regime remains important to how the system will work in practice. [4]
That distinction is practical. An older building may still have deteriorated materials, weak parapets, maintenance issues, undocumented alterations or other structural concerns unrelated to whether it sits on the EPB register. Owners still need to respond to visible damage, professional findings and other lawful requirements that apply to the property.
What the reform does not remove
The change does not remove the Building Code, building consent requirements, code compliance processes, council powers relating to dangerous or insanitary buildings, or the need to maintain a property. Fire safety, accessibility, specified systems and change-of-use requirements may still apply depending on the building and proposed work.
Insurance, lending and lease requirements are separate considerations. An insurer, lender or tenant may still ask for structural information even where a statutory EPB designation is removed. Owners should check those documents directly rather than assuming the legislative change answers every risk or investment question.
Before changing a strengthening or renovation plan
Start with the current notice and property record. Ask the territorial authority whether the designation remains active, whether a change has taken legal effect and what updated record will be issued. Keep written confirmation with the building file.
Then review the project with the relevant advisers. A structural engineer can explain whether completed investigations still identify useful maintenance or risk-reduction work. The designer and builder can separate statutory seismic work from renovation, weatherproofing, fire, access or service upgrades. Legal, insurance and financial advisers can confirm the effect on contracts, policies, loans and leases.
Keep the decision trail clear
A good project file should retain the original EPB notice, council correspondence, engineering reports, drawings, estimates, contracts, variations and any updated register record. Record why the scope or programme changes and who approved the decision. That history will help a future owner, insurer or project team understand what was assessed and what was not.
If work continues, update the brief and budget so everyone is working from the same purpose. A project may shift from mandatory strengthening towards targeted maintenance, façade work, adaptive reuse or a wider renovation, but that should be an informed decision rather than an assumption drawn from a headline.
The bottom line
The reform is significant for Northland property owners because the region is set to leave the statutory earthquake-prone building system. The sensible next step is verification. Check when the change legally applies, obtain the updated council position and review existing project, insurance and contract commitments before changing course.
This article is general information only. The status, condition and obligations for a building depend on its location, records, use, structure and project arrangements. Confirm the current position with the relevant council and suitably qualified engineering, legal, insurance and construction advisers before making decisions.
