Fuel Price Squeeze, the OCR and Building today

New Zealand has been here before. Fuel price spikes tied to global oil shocks, most notably in the 1970s, in 2008, and again in 2022, have repeatedly pushed up the cost of living without any deliberate move from the Reserve Bank. In each of those episodes, higher petrol prices acted like an informal tax on households, pulling money out of discretionary spending and household budgets alike.

In several of those cycles, the Reserve Bank held or even raised rates too long while chasing a fuel driven inflation number, only to cut hard once it became clear the underlying economy, jobs, and consumer demand, had weakened well ahead of the official data. History suggests fuel shocks and OCR settings do not always move in step, and getting the timing wrong in either direction has real costs for households and for anyone planning a build.

The current setting has a specific driver. Inflation has been running above the Reserve Bank's 1 to 3 percent target, largely due to conflict in the Middle East pushing up petrol and diesel prices in New Zealand. On the surface that looks like a reason to hold or lift the OCR. But look underneath the headline number and the picture is less convincing.

Consumer demand remains soft, unemployment has stayed stubbornly elevated, and much of the current inflation reading is being driven by a cost push shock at the petrol pump rather than genuine strength in spending or borrowing. That is an important distinction. A demand led inflation problem justifies higher rates. A fuel led spike sitting on top of a weak labour market and cautious consumers looks more like a temporary distortion than a signal to keep tightening.

It would not be the first time the Reserve Bank has read a fuel shock as more persistent than it turned out to be, and there is a genuine case that rates should be heading down in 2027 to support consumer spending and get the economy moving again, rather than up.

We are seeing this play out directly with clients in Remuera and across Auckland's eastern suburbs right now. Land values here have held firm even as build costs have climbed, and that combination changes the calculation for anyone sitting on a section or an ageing home and weighing whether to commit to an architectural rebuild.

Whichever way the OCR moves next, construction costs are on a one way track upward. Materials, labour, compliance, and land are all more expensive today than they were a year ago, and that trend is not reversing. That means today is, in all likelihood, the cheapest it will ever be to build. Waiting for the perfect rate environment risks missing the actual cost advantage sitting in front of you right now.

If rates do ease through 2027 as softer demand and high unemployment would suggest they should, that eases mortgage and financing costs on top of locking in today's build price, which is about as good a combination as a homeowner can hope for. Nobody can call the Reserve Bank's next move with certainty, and some days it genuinely is anyone's guess. But for Remuera homeowners weighing up an architectural build, the maths on waiting rarely improves.

Starting the design process now, with one team carrying the project from concept through to Code Compliance Certificate, means you lock in today's costs while the finance picture still has room to improve alongside you. If you're thinking through what a new build or major renovation could look like on your Remuera site, our architectural design and build team is a good place to start.
