What Does a Renovation Actually Cost in Tauranga?

Let’s cut to it. If you’re Googling “renovation costs Tauranga,” you want numbers, not waffle. So here are the realistic ranges we’re seeing across our projects in 2025.

The Ballpark Numbers

Kitchen renovations: $20,000 to $60,000 for a mid-range result. That covers new cabinetry, benchtops, appliances, and flooring. Push into custom joinery, stone benchtops, and high-end appliances, and you’re north of $60k. The scullery-behind-the-kitchen trend? Budget accordingly — it’s essentially a second small kitchen.

Bathroom renovations: $15,000 to $40,000 depending on size and spec. The freestanding bath, floor-to-ceiling tiling, and heated flooring combination that everyone’s after sits in the upper half of that range.

Recladding: $150,000 to $350,000+ for a standard three-bedroom home, depending on the extent of damage found behind the existing cladding. This is one of those projects where the final cost depends heavily on what the builder discovers once the old cladding comes off.

Home extensions: Starting around $3,000–$4,500 per square metre for a straightforward single-level addition. Second storeys, complex engineering, and premium finishes push that higher. A meaningful extension typically starts around $150,000 and can exceed $400,000 for larger or more complex projects.

These aren’t marketing numbers — they’re based on what we’re actually building for clients across Tauranga, Papamoa, and Mount Maunganui.

What Actually Drives the Cost?

The size and scope of the project is the obvious one. But here are the factors that often surprise people:

Materials and finishes make an enormous difference. The gap between a laminate benchtop and a 40mm stone slab isn’t just aesthetic — it can be $5,000–10,000 on that one item alone. Multiply that across every surface, fixture, and fitting in a kitchen or bathroom, and material choices can easily double the project cost.

What’s behind the walls is the big unknown in renovation work. Asbestos, outdated wiring, non-compliant plumbing, structural issues, moisture damage — you don’t know until you open things up. This is why we always recommend a 10–20% contingency fund on top of your renovation budget. It’s not pessimism; it’s reality.


Design and planning costs money upfront but saves money overall. Working with an experienced designer or architect means fewer changes during construction, fewer mistakes, and a better end result. Skipping this step to save $5,000 usually costs $15,000 in changes and rework.


Labour market conditions fluctuate. Skilled trades in the Bay of Plenty are in demand, and that demand affects pricing. This isn’t something you can control, but it’s something to factor in when comparing quotes.

How to Keep Your Renovation Budget on Track

  • Prioritise ruthlessly. Spend big on the things that matter to you daily and economise on the rest. A $2,000 tap fitting and a $200 one both deliver water.
  • Decide everything upfront. Changes mid-build are the single biggest budget killer. Every time you change your mind after work has started, it costs you time and money.
  • Keep what works. Repainting existing cabinetry, keeping a good layout, or retaining fixtures that are still in good condition can save thousands without compromising the result.
  • Build your contingency into the budget from day one. Not as an afterthought. If your real budget is $200k, plan a $170k project and keep $30k in reserve.
  • Get a fixed-price contract. It removes the guesswork and means the price your builder quotes is the price you pay. We offer this as standard at Davy Construction.
