Mike and Jo bought a lifestyle block outside Kerikeri with one idea: cut off the back paddock, sell it, and pay down the mortgage. They did everything in the right order, or so they thought. Surveyor, engineer, resource consent. Eight months in, with the plans stamped, they walked into their bank. The answer was no. Six months and one expensive non-bank loan later, most of their margin had gone.
This post is for small and single-operator developers, from a one-lot subdivision to a handful of townhouses. You’ll read why a slow market is a good time to secure land, what’s happening to costs and rates, how lenders are judging development deals in 2026, and the sum that shows how Mike and Jo lost most of their profit without a single thing going wrong on site. You’ll finish knowing which numbers a lender will test first.
The short version: Sellers are negotiating: homes take a median 51 days to sell and stock is up 9.7% [1]. Build costs are up 3.5% a year [5] and the OCR is rising [4]. On a small subdivision, time is the most expensive line in the budget. Plan the finance before you commit to the land.
Is now a good time to buy land to subdivide?
For well-prepared developers, it can be. You buy in the slow part of the cycle and sell into the next one. With listings up and sales down [1], sites are more negotiable and conditional offers get a fairer hearing (my read of the data). Northland’s median price rose 3.6% in the year to August, even as seven of the eight North Island index series fell over the last three months [2].
Don’t bank on a quick rebound. The Reserve Bank of New Zealand expects a modest recovery in house prices [4]. ASB doesn’t see nominal prices regaining their 2021 peak until late 2029 [6]. Build your plan on today’s values, not tomorrow’s.
What’s happening to development costs and interest rates?
Both are heading up. The Cordell Construction Cost Index rose 3.5% in the year to June 2026, the fastest rise since mid-2023. Cotality’s Kelvin Davidson says the “exceptionally quiet period for construction cost inflation is probably behind us” [5]. New home consents rose 11% to 37,813 in the year to March [3], so contractors are getting busier again.
The OCR went to 2.75% on 2 September and may need to rise further [4]. Markets are pricing a peak around 4% [7]. Development debt sits well above home loan rates, so every move lands on your holding costs.
How much does a delay cost on a small subdivision?
Mike and Jo’s numbers (illustrative). A $1.1 million lifestyle block plus $180,000 for survey, consents, engineering, access and services, with $430,000 of their own equity. The loan is $850,000 at an assumed 9% development rate, plus a 2% establishment fee. Planned as a 12-month project, with the new lot selling for $450,000 and the house on the balance land worth about $1 million, the plan leaves them roughly $63,000 ahead after interest, fees and selling costs.
Now add the six months they lost finding a lender. That’s about $38,000 of extra interest, and their $63,000 margin shrinks to about $25,000. That’s 60% gone, and nothing went wrong on site. Timber prices didn’t do that. The calendar did.
How are lenders assessing development deals in 2026?
Banks are still lending, but they’re selective. Non-bank lenders are winning deals on speed and flexibility. Funders are favouring smaller, simpler, staged projects. Presales are less of a hard rule, and many lenders look harder at the residual loan-to-value ratio and whether the finished property could be refinanced [8]. In plain terms, they want to know your plan if the lot doesn’t sell straight away.
What should small developers watch?
- Your exit. At a 51-day national median [1], lifestyle lots can take longer. Model realistic selling times, plus the interest while you wait.
- A hold plan. If the lot doesn’t sell, can you carry it, or build and rent? Lenders like a second exit.
- The small play. Standalone dwellings up to 70 square metres can now be built without a building consent if they meet the exemption conditions [9]. On a lifestyle block, that can add income while you hold.
- Contingency. With costs rising again, a thin contingency is the first thing a lender will question.
- Tax. Labour’s proposed 28% tax on residential investment gains from 1 July 2027 isn’t law [10], but development profits have their own tax rules. Get tax advice on your structure before you buy.
What would have saved Mike and Jo’s margin?
One phone call, before they signed for the land. It’s the most common and costly mistake I see: a developer buys the site, designs the project, then goes looking for funding. By then, the decisions that shape the lending have already been made.
A broker worth their salt understands the whole project: the land, the works, the timeline, your wider finances and the exit. Brought in at the start, I can help shape and coordinate the deal so it’s attractive to a lender. I can look at less obvious structures that reduce risk and interest costs, such as staging, a mix of bank and non-bank funding, or a hold-and-refinance exit. And I can model what happens to your margin if costs, rates or selling times move before you’re committed.
That preparation gives lenders confidence, and the broker behind an application carries weight. On a complex project, experience you can lean on can be the difference between a deal that gets funded on time and one that stalls. That’s my experience, and it’s always subject to lender assessment.
F.A.Q
Do I need presales to get development finance in NZ?
Not always. Presales help show demand, but in 2026 many funders focus more on the residual loan-to-value ratio and whether the finished property can be refinanced [8].
Should I use a bank or a non-bank lender for a subdivision?
Banks are usually cheaper but slower and stricter. Non-banks cost more but can move faster on deals outside bank policy [8]. Compare the total cost including any delay, not just the interest rate.
How fast are NZ building costs rising?
The Cordell Construction Cost Index rose 3.5% in the year to June 2026, the fastest annual rise since mid-2023 [5].
