Amalgamation

Amalgamation is the reverse of subdivision — it combines multiple adjoining titles into one. In New Zealand, amalgamation is typically done when a property owner purchases a neighbouring property and wants to merge the two into a single title, or when council subdivision consent conditions require it.

Amalgamation conditions are sometimes imposed by councils as part of resource consent for subdivision or land use. For example, a council might consent to a new dwelling on a rear lot on the condition that the rear lot is amalgamated with an adjoining lot to create a viable site.

The process requires a surveyor to prepare a new survey plan and a lawyer to handle the LINZ registration. It's simpler and cheaper than subdivision because it typically doesn't require resource consent (unless it's a condition of another consent).

If you're buying a property that has an amalgamation condition on the title, understand what it requires. Some amalgamation conditions prevent you from selling the property separately from an adjoining lot — effectively tying the two properties together.

Check whether any amalgamation conditions have been satisfied or are still outstanding. Outstanding conditions can restrict what you can do with the property and complicate future sales.

Amalgamation conditions are recorded on the certificate of title as a memorial. Your lawyer should identify and explain any amalgamation conditions during the title search. Check with the council whether the conditions have been met or are still outstanding.

If you're considering amalgamating titles you already own, consult a surveyor and lawyer to understand the process and costs.
