Short answer
Built granny flat units in NZ have a median starting price of $91k, unit only. Published 70 m² two-bedroom units sit between $145k and $299k for the unit alone.
Work out the all-in costUp to 70 m² needs no building consent since 15 January 2026 if the flat is new, detached and single storey, sits 2 m clear of boundaries and other buildings, shares a site with an existing home, and licensed people do the work. You still need a PIM from council.
Check if you can skip the consent (2 min)Counts include builders who offer more than one type, so they add up to more than 143.
Most transportable builders deliver nationwide, which is why the counts are close. Use the type and size filters to narrow it down.

How to choose
Ask each builder for a site-specific price with transport, foundations and connections in it. The unit is often only 55 to 70 percent of what you will spend.
Show builders with a published priceBase spec, GST, a kitchen, a bathroom, decking, curtains, heat pump. Two '$150k' flats can be $40k apart once you add the gaps.
Turnkey means one company is responsible for everything. Kitset is cheaper but you manage the trades. Site-built suits sloping or tight sections a truck cannot reach.
Show turnkey buildersUnder the 2026 exemption someone still has to get the PIM, collect the Records of Work and file the completion notice. Make it the builder, in writing.
Show builders with 70 m² designsA Master Build or Halo 10-year guarantee covers you if the builder fails to finish. Membership of Master Builders or NZ Certified Builders is a reasonable first filter.
Show master builders membersYard slots book out. Avoid paying more than about 10 to 20 percent before construction starts, and tie the rest to stages you can see.

We started from 163 businesses that advertise granny flats, cabins or minor dwellings in New Zealand and kept the 143 whose websites are live. Every card shows the date we last read the builder's site.
Prices are the lowest figure each builder advertises, with the GST basis they state. Where we could not tell what a number referred to, we left the price off. Builders change prices often, so confirm before you budget.
No builder pays to be listed, and the order is never for sale. If we add paid placements or referral links later, they will be labelled, and they will not change the order of the directory.
