Builders in Tauranga & the Bay of Plenty
Custom homes and renovations, built by a local, family-owned Master Builder
Diack Homes is a family-owned builder based in Papamoa. Since 2020 we've built new homes and renovated existing ones across Tauranga and the wider Bay of Plenty. Cameron Diack, our director, is a Licensed Building Practitioner and Registered Master Builder. In 2026, homes we built won a category award and two Gold Awards at the Master Builders Bay of Plenty & Central Plateau House of the Year.
Every section here is different. A hillside site in Welcome Bay, a beachfront section in Papamoa and a lifestyle block near Te Puke all raise different questions. This page covers what we build, where we've built, how pricing works and what to check before you commit.
Award-winning homes in the Bay of Plenty
Here's what we've recently built and renovated in the region. Each project page has the full gallery.
The 2026 awards were judged by Master Builders across the Bay of Plenty and Central Plateau. Both of our winning homes are in Paengaroa, on the Te Puke side of Tauranga.
View all projectsWhat we build and renovate in the Bay of Plenty
All of our renovation services are delivered in the Bay of Plenty by our Papamoa-based team.
- Custom homes: architecturally designed or plan-based homes, tested against your section, specification and budget before you commit.
- Knockdown rebuilds: demolition through to a new home on the section you already own.
- Full home renovations in Tauranga: structural changes, new layouts, re-roofing, insulation and interiors.
- Home extensions: extra bedrooms, living areas or a second storey. An engineer checks that the existing structure can carry the load.
- Bathroom renovations: waterproofing, ventilation and materials chosen for the room and the site.
- Recladding and weathertightness: we diagnose the cause first, then choose a cladding system that suits the site's exposure.
- Pole sheds: for farms, orchards and rural properties, from feasibility and consent to construction.
The team behind your build
The owners stay involved in every job. Cameron Diack oversees every project. Zoe Diack runs the business systems and administration. On site, Damien Quarry is our project manager and a licensed builder. He placed second in the Bay of Plenty Apprentice of the Year. Dave Behrent is our foreman, and Mike, a qualified carpenter and LBP, has more than ten years' experience. Dale Horton (qualified builder) and Noah Lord (apprentice) complete the crew.

Areas we build across the Bay of Plenty
We build from Te Puna and Minden in the west to Whakatāne and Kawerau in the east. Each part of the Bay has its own ground conditions, exposure and council, and those affect design, consent and price.
Tauranga
Tauranga ranges from flat harbour-edge sites to steep hillside sections, from Ōtūmoetai and Bethlehem to Welcome Bay. Retaining, earthworks and foundation design vary from suburb to suburb, so we assess them for your section before we finalise a price. Consents go through Tauranga City Council.
Mount Maunganui and Papamoa
Coastal sites need materials rated for salt air: marine-grade fixings, drained cavities and cladding that suits the site's exposure zone. Check the council's coastal and harbour inundation maps before you design. Our office is in Papamoa. See renovations and home builders in Papamoa and building in Mount Maunganui.
Te Puna, Minden, Paengaroa and Te Puke
Te Puna, Minden and Paengaroa sit within the Western Bay of Plenty District Council, which handles consents there. Our two 2026 Gold Award homes are in Paengaroa, near Te Puke. If you're building or renovating in or around the town itself, see building in Te Puke.
Maketu
Maketu is a small coastal settlement beside the Kaituna River estuary, with a mix of long-held family properties, baches and newer homes. Parts of it are mapped for land instability and coastal erosion. Depending on how close the site is to the coast or estuary, Bay of Plenty Regional Council consent may be needed for earthworks or stormwater. Geotechnical investigation comes before pricing.
Edgecumbe
Edgecumbe sits on the low-lying Rangitāiki Plains, which the 2017 stopbank breach flooded. River-deposited soils vary in bearing capacity, and some areas have high water tables. Check the site's flood hazard status with Whakatāne District Council before design. Older homes being renovated should also have their structure assessed against current seismic requirements.
Kawerau
Kawerau sits partly over an active geothermal field, on volcanic ash and pumice soils. Foundations need a geotechnical investigation first. Much of the housing dates from the town's 1950s founding, so renovations start with a condition assessment that includes testing for asbestos. Kawerau District Council is its own building consent authority.
Whakatāne
Ground conditions in Whakatāne change from pumice on higher ground to soft alluvial soils near the river and the Ōhope estuary. Coastal and river sites need materials and floor levels that respond to the verified hazard information. Whakatāne District Council handles consents, and development contributions vary by project.
What does it cost to build or renovate in the Bay of Plenty?
No single price range fits every Bay of Plenty project. The biggest variables are the site, the design, the specification, access, the condition of the existing home and the consent pathway. Use the online estimate as a starting range. Your fixed price comes after we've assessed the site and documented the plans and specification.

Our Project Checklist takes every job through eight stages:
- Enquiry information: we record your project and the information we have so far.
- Job brief: we define the work, your priorities and what still needs to be found out.
- Plans: we prepare and review the plans needed for pricing.
- Pricing: we price the documented scope, with assumptions, inclusions and exclusions written down.
- Quote presentation: we walk you through the price and what it's based on.
- Contract and guarantee: we sign the building contract, and you apply for the Master Build 10-Year Guarantee if you choose it.
- Job set-up: we confirm the site set-up, responsibilities, programme and how we'll keep you updated.
- Project close: handover, plus your warranty and guarantee documents.
During the build you get progress updates, photos and documents through Buildertrend.
Your protections
- Fixed-price contract: your scope, price, inclusions, exclusions and payment schedule are documented before work starts. Ask us how requested changes are handled.
- Gold Standard Promise: our own quality standards, quality control checklists, regular inspections, clear communication and cost transparency.
- Master Build 10-Year Guarantee: as Registered Master Builders, we can offer it. It's separate from the building contract and must be applied for and accepted before building work starts. Accepted cover can include loss of deposit, non-completion, materials and workmanship, structural defects and temporary accommodation, subject to the issuer's current terms.
Frequently asked questions
Are you renovators as well as new home builders?
Yes. In the Bay of Plenty we do full home renovations, extensions, bathrooms and recladding, as well as custom homes and knockdown rebuilds.
Do I need council consent for my renovation or extension?
Most extensions and structural renovations need building consent. Some low-risk work is exempt under Schedule 1 of the Building Act 2004. We confirm the pathway for your project and manage the consent for you.
Can you price plans I already have?
Yes. We'll check your plans against your site, specification and budget before pricing. If you don't have plans yet, we can work through the design with you.
How long does a custom home take to build in the Bay of Plenty?
It depends on the design, site conditions, consent pathway and scope. You'll get a project-specific programme before you commit. Our custom home building timeline explains each stage.
Which areas do you cover?
Tauranga, Mount Maunganui, Papamoa, Te Puna, Minden, Te Puke, Paengaroa, Maketu, Edgecumbe, Kawerau, Whakatāne and the wider Bay of Plenty.
