A Step-by-Step Guide to Residential Subdivisions
24 September 2024

Subdividing a residential property can be quite complicated, and may take a lot of time. However, with thoughtful planning and the right help from professionals, it can also be a very rewarding project. This process involves breaking up a larger piece of land into smaller sections, which can then be sold or developed separately.


To make this journey easier for you, we’ve put together a detailed guide. This guide will walk you through each step of the subdivision process, helping you understand what to expect and how to prepare. With the right information and support, you can successfully navigate this process and achieve your goals.


1. Consult the Council

Before starting a subdivision project, consult with your local council. They can tell you if dividing your property is possible, and identify any restrictions or requirements that may apply. The council will explain zoning laws, minimum lot sizes, and other important regulations.


2. Check with your Lender

If you have a mortgage on your property, it’s crucial to check with your lender to ensure they consent to the subdivision. Subdividing a mortgaged property can affect your loan terms, and your lender might need to issue new mortgage documentation.


3. Engage a Surveying Company

You will need to hire a surveying company to draft subdivision plans and determine what utilities are required. The surveyor will prepare a resource consent application to present to the council for approval. They will also coordinate with utility companies to arrange any required physical works and easements. Easements may include rights of way, the right to convey electricity, telecommunications, water, sewage, and stormwater.


The surveyor will work closely with the council to obtain the necessary certifications and lodge the documentation with Land Information New Zealand (LINZ). Be prepared to pay a development levy to the council before final approval is granted. Once all work is completed and the council has signed off on the subdivision plan, the final plan – the ‘deposited plan’ is lodged with LINZ.


4. Involve Your Lawyer

Let your lawyer know about your plans to subdivide early on. They will work with the surveyor and your bank to get approval for the subdivision and manage any new mortgage paperwork.  Your solicitor will also advise on and prepare land covenants, which can impose restrictions on the subdivided properties. These covenants might limit the size or height of buildings, specify building materials, or regulate planting and property maintenance.


Your lawyer will prepare new title and easement documentation, and you will need to sign these documents to finalise the subdivision.



Subdivisions involve multiple parties and can be expensive. It’s wise to obtain cost estimates from the council, surveyor, and lawyer before committing to the process. Understanding the financial and time commitments involved will help you make informed decisions and ensure a smoother subdivision experience.

1. Myth: “The Property Relationships Act applies after 2 years!” - Wrong Generally, the time period for a relationship to become what is known as a qualifying relationship under the Property (Relationships) Act 1976 is 3 years from the commencement of the relationship. This time period can be shorter if there is a child in the relationship or the applicant has made a substantial contribution to the relationship. The 2 year period is the period a married couple must be separated before the marriage can be dissolved (i.e. divorced). 2. Myth: “It’s my property – I can leave it to whomever I want!” Wrong (sort of) This statement highlights the tension between what lawyers refer to as “testamentary freedom” that a Will-maker has and rights certain persons have under various statutes and law. While it is true that a Will-maker can do what they want with their property, this is not absolute. A Court can order a different distribution where a Will-maker fails in what is known as their “moral duty” to make “proper maintenance and support” for family members. In addition partners have rights under the Property (Relationships) Act 1976, and the Law Reform (Testamentary Promises) Act 1949 can assist persons to whom the Will-maker has made promises to provide for them in return for work or services done in the Will-maker’s lifetime. The rules of equity may also affect the Will-maker’s testamentary freedom. 3. Myth: “I’ve been in a relationship for 30 years so surely I can make decisions for my partner who has lost mental capacity!” – Wrong Despite the length of a relationship (marriage/de facto/civil union) if one of the partners loses mental capacity the other partner has no right to make decisions for their incapacitated partner in relation to their property and/or their personal care and welfare, unless the incapacitated partner has completed Enduring Powers of Attorney. If the incapacitated partner has not completed Enduring Powers of Attorney applications to the Family Court will need to be made for the appointment of a Property Manager (or Administrator if there are not significant assets) and a Welfare Guardian. 4. Myth: “I can buy/sell a house without a lawyer involved” – Wrong (sort of) In theory, a layperson can buy or sell a home without the involvement of a lawyer but (and it is a big but) it would be very difficult to do so (not to mention the risk of doing so). If bank lending is involved, the bank will insist on the involvement of a lawyer to act on its behalf and may even decline to lend if a buyer is not legally represented. Even if the bank was prepared to lend it is likely it and its lawyers would impose so many conditions and requirements (in order to protect the bank’s position) that it may be practically too difficult for a buyer act for themselves. Furthermore, with the land register now being predominantly electronic, relying on lawyers with the requisite certifications, it will be difficult for a non-licenced person to transact the registrations. Again, in theory, these can be done manually in paper form but the formalities involved in doing so is likely to make it practically difficult (if not impossible) for a buyer or seller to do so. This is general information about the current law, not advice on a specific matter. Article by: Kevin Callinicos
