Relocating a house in Northland is one of the most cost-effective ways to get onto a property — but it's rarely as cheap as people first assume. The purchase price of the house is just the beginning. By the time you've paid for transport, foundations, services, consents, and the inevitable surprises, the total project cost is typically 2–3 times the purchase price.

Here's an honest breakdown of every cost category, based on community-reported figures and Northland contractor rates.

The House Purchase Price

Second-hand relocatable houses in Northland range from around $20,000 for a small, tired cottage to $80,000+ for a larger, well-maintained home in good condition. Most 3-bedroom homes in reasonable condition sell for $40,000–$65,000.

Lifting & Transport

This is typically the second largest cost. Transport pricing depends on distance, route complexity, house size, and whether the house needs to be split. Rough ranges for Northland moves:

• Short local move (under 20km): $10,000–$18,000
• Regional move (20–80km): $18,000–$30,000
• Long distance (80km+): $30,000–$50,000+
• Add 30–50% if the house needs to be split for transport

Foundation Work

Foundations are where costs vary most wildly — and where people most often underestimate. The type of foundation and ground conditions at your receiving site drive the price:

• Timber piles on good flat ground: $15,000–$25,000
• Concrete piles: $25,000–$40,000
• Concrete slab: $30,000–$50,000
• Difficult ground (wet, steep, soft): add 50–100%

Services Connection

Connecting water, wastewater, power, and potentially gas is a significant cost that's easy to forget when you're focused on the house and transport:

• Power connection: $2,000–$6,000 depending on distance to transformer
• Water supply (town supply): $1,500–$4,000
• Wastewater (septic system for rural sites): $8,000–$20,000+
• Reticulated wastewater (town supply): $3,000–$8,000

Consents & Engineering

Building consent fees are set by each council and vary based on project complexity. Budget:

• Building consent fees: $3,000–$8,000
• Structural engineer's report on the house: $800–$2,500
• Foundation design by registered engineer: $1,500–$4,000
• NZTA transport permits: $300–$1,500

Contingency

Every experienced person we've spoken to says the same thing: budget at least 15–20% contingency on top of all other costs. Relocated houses always have surprises — hidden rot, wiring that needs replacing, ground conditions worse than expected.

A Realistic Total

For a typical 3-bedroom house, regional move, reasonable ground conditions:

• House purchase: $50,000
• Transport (regional): $22,000
• Foundations (concrete piles, average ground): $28,000
• Services (full connection): $18,000
• Consents & engineering: $9,000
• Contingency (15%): $19,000
• Total: ~$146,000

Relocating a house is a complex, multi-step project with a lot of moving parts — literally and figuratively. After reading through hundreds of community forum posts and talking to people who've been through it, these are the mistakes that come up again and again.

1. Moving the House Before Getting Consent

This is the single most common and most costly mistake. It seems logical — move the house first, then sort out the paperwork. But under the Building Act, you cannot lawfully occupy a relocated dwelling until a Code Compliance Certificate has been issued. And you can't get a CCC without a building consent. And the consent process must start before the house moves.

2. Not Checking the Receiving Site Early Enough

People often fall in love with a house and buy it before they've properly assessed their receiving site. Then they discover the site is in a coastal hazard zone, needs a resource consent, has terrible ground conditions, or can't be connected to wastewater without a $25,000 septic system. Do the site due diligence first — before you buy the house.

3. Underestimating Foundation Costs

Foundations are consistently the biggest budget blowout in relocatable house projects. The quotes people get before the geotechnical report comes back are often optimistic. Once the geotech reveals difficult soil conditions — expansive clay, soft alluvial soils, high water table — foundation costs can double or triple.

Get the geotechnical report done early. Budget for the worst case. Then be relieved if it comes in better than expected.

4. Forgetting About Overhead Lines Along the Route

Your contractor needs to notify power lines companies well in advance of the move — typically 2–4 weeks minimum. If overhead lines need to be raised or temporarily disconnected along the route, this takes time to organise and costs money. Forgetting about this step can delay your move date significantly and result in rushed decisions.

In most of Northland this means notifying Northpower. In the Far North it's Top Energy. Check with your contractor early in the planning process.

5. Not Getting the Code Compliance Certificate

Once the house is on site and all the work is done, many people move in and consider the job finished. But without a Code Compliance Certificate, the house is not legally habitable. This creates problems when you try to sell, refinance, or insure the property. The CCC is not optional — apply for it as soon as all inspections are passed.

Moving a house in Northland isn't just about getting from A to B. A loaded house transporter — house, trailer, tractor — can easily weigh 40–50 tonnes. Many of Northland's rural bridges have weight limits of 3–8 tonnes. The gap between those two numbers is what makes route planning so critical.

Why Northland Has So Many Restricted Bridges

Northland's roading network includes a large number of older bridges, particularly on rural roads and secondary state highways. Many were built to earlier standards and haven't been upgraded to carry modern heavy vehicle loads. NZTA maintains restriction data but it changes — bridges are upgraded, restrictions are added after storm damage, and temporary weight limits are imposed from time to time.

What "Weight Restricted" Actually Means

Bridge weight restrictions are posted as the maximum gross vehicle mass (GVM) that can cross. A restriction of 8 tonnes means no vehicle — including the load — can exceed 8 tonnes. A standard house on a transporter will far exceed this. Your contractor must plan a route that avoids restricted bridges or obtain special permits and engineering assessments to cross them.

Key Restricted Routes to Know

• SH12 at Matakohe: The Matakohe bridge is one of the most commonly encountered restrictions for moves between Dargaville and Whangārei. Check current status with NZTA before planning this route.
• SH14 at Tinopai Road: 5 tonne limit makes this effectively impassable for loaded transporters.
• Rural roads generally: Assume any rural road bridge in Northland is restricted until proven otherwise. Always confirm with your contractor.
• Far North rural bridges: The Far North has many 3–8 tonne rural bridges. Routes to remote properties often require significant detours.

Height Restrictions and Power Lines

Bridge weight limits aren't the only route constraint. Height restrictions (typically 4.25m without a permit on state highways), overhead power lines, and low clearances under bridges all affect route planning. Most houses need to be lowered off their foundations before transport to comply with height limits.

How to Plan Around Restrictions

• Use the FillFinder Bridge Restriction Checker for known restrictions on main Northland routes
• Call NZTA on 0800 699 000 for current permit information and route assessments
• Ask your contractor to assess the route before quoting — experienced Northland contractors know which roads to avoid
• Allow 10+ working days for standard NZTA oversize permits
• For police escort moves (over 4.3m wide), allow longer and budget for the additional cost

What Happens If You Get It Wrong

Attempting to cross a weight-restricted bridge without approval is a serious offence under the Land Transport Act. It can result in significant fines, and if bridge damage occurs, the costs can be enormous. Beyond the legal risk, a bridge failure mid-move is a catastrophic outcome for everyone involved. This is not an area to cut corners.
