Rules relating to subdivision and minimum allotment size are found in the subdivision chapter. This is located in Part 2: District Wide Matters. SUB-S1 has a list of minimum lot sizes depending on what zone you are in.
It is important to note that all subdivision requires resource consent. However, there is a spectrum of consents ranging from controlled to non-complying. Broadly speaking, controlled is the most straight forward resource consent to apply for as these must be granted by Council, whereas non-complying is where subdivision is generally being avoided, and consents are only granted in exceptional circumstances.
If you want to create lots smaller than this minimum, see the relevant rule in the subdivision chapter for what type of consent is required. You should also check if your property has any other planning considerations such as landscapes, significant natural areas or natural hazards as this may change what type of consent is required.
- Creating lots 2ha in size in the Rural Lifestyle Zone is generally a controlled activity
- Creating lots 2ha in size in the Rural Lifestyle Zone within a Special Amenity Landscape would be a discretionary activity
- Creating lots 2ha in size in the Rural Lifestyle Zone where a building platform is to be built in a stream corridor would be a non-complying activity.
