How much does concreting cost in New Zealand?

The answer depends on much more than the amount of concrete required. Site preparation, concrete thickness, reinforcement, access, drainage, finish and the type of project can all significantly affect the final price.

This guide explains what influences concrete costs, how square-metre pricing works and what to consider when budgeting for your project.

How Much Does Concrete Cost Per Square Metre in NZ?

For professionally installed exterior concrete, current New Zealand pricing guides commonly show rough indicative rates of around $100–$200+ per square metre for concrete driveways, depending on the project and finish.

Decorative options such as exposed aggregate, coloured or more specialised concrete finishes can sit towards the higher end or above standard concrete pricing.

These figures should only be used for preliminary budgeting.

A square-metre rate may or may not include:

Excavation
Base-course preparation
Reinforcing
Boxing
Concrete supply
Concrete placement
Surface finishing
Existing concrete removal
Drainage
Concrete pumping
Disposal costs
Travel or difficult site access

This is why two concrete projects of exactly the same size can have very different final prices.

The most accurate way to establish concrete cost is to get a quote based on the actual project and site.

Concrete Driveway Cost NZ

Concrete driveways are one of the most common projects where customers search for a price per square metre.

As a broad guide, installed concrete driveway costs in New Zealand can commonly fall around the $100–$200+ per m² range, with the final figure heavily influenced by preparation and finish.

A basic driveway on a flat, easily accessible site may cost considerably less than a decorative driveway that requires:

Removal of existing concrete
Significant excavation
Additional base preparation
Drainage
Concrete pumping
Heavier reinforcement
Difficult access
Exposed aggregate or decorative finishing

For example, a 50m² driveway is not simply the concrete price multiplied by 50.

The contractor also needs to consider everything required to get the site ready before the concrete truck arrives.

What Affects Concrete Driveway Cost?

Several factors can have a significant effect on the final driveway price.

Driveway Size

Larger driveways require more:

Concrete
Reinforcement
Base material
Boxing
Labour

However, larger projects can sometimes achieve a better square-metre rate because setup and other fixed costs are spread across a greater area.

Ground Preparation

What is underneath the concrete matters.

The area may require:

Excavation
Removal of topsoil
Removal of unsuitable material
Base-course installation
Compaction
Levelling

A site that is already well prepared can therefore cost less than one requiring extensive earthworks.

Concrete Thickness

Concrete thickness should reflect the intended use of the surface.

A residential path does not necessarily require the same specification as a driveway regularly carrying vehicles.

Similarly, areas used by heavy vehicles, trucks, forklifts or machinery may require a heavier-duty concrete design.

More concrete per square metre generally means a higher material cost.

Reinforcement

Reinforcing mesh or steel may be required depending on the project.

The amount and type of reinforcement can affect both material and labour costs.

Site Access

Easy access can make a substantial difference.

If a concrete truck can pull alongside the area being poured, placement may be relatively straightforward.

More difficult sites can involve:

Narrow access
Rear sections
Steep properties
Long distances from the road
Obstacles between the truck and pour

In these situations, additional labour or a concrete pump may be required.

Drainage

Drainage can add cost but is an important part of many exterior concrete projects.

This may involve:

Channel drains
Additional excavation
Connections to existing drainage
Careful surface falls
Managing runoff around garages and buildings

Correcting drainage while the concrete is being installed is usually preferable to discovering water problems afterwards.

Plain Concrete Cost vs Exposed Aggregate

One of the biggest pricing decisions for visible concrete areas is the type of finish.

Plain Concrete

Plain or standard finished concrete is generally one of the more economical options.

It can be suitable for:

Driveways
Utility areas
Shed floors
Garage floors
Paths
Some patios

A broom finish can also be applied to create additional surface texture.

Exposed Aggregate Concrete

Exposed aggregate concrete involves additional finishing work to reveal the aggregate within the surface.

It is commonly used for:

Driveways
Entranceways
Patios
Paths
Pool surrounds

Because of the additional materials and finishing process involved, exposed aggregate will generally cost more than straightforward standard concrete.

Coloured & Decorative Concrete

Adding colour or other decorative treatments can increase the price further.

The best way to compare options is to request pricing for two or more finishes on the same project, rather than comparing unrelated online square-metre rates.

Concrete Patio Cost NZ

The cost of a concrete patio in NZ depends on its size, access, preparation and finish.

Patios may sometimes be less demanding than vehicle driveways because they are not carrying the same loads.

However, pricing can increase where the project involves:

Significant excavation
Difficult backyard access
Concrete pumping
Decorative finishes
Steps
Complex shapes
Drainage
Connections to existing outdoor areas

For an outdoor living area, it can be worthwhile comparing the cost of plain, broom-finished and exposed aggregate concrete before deciding on the final specification.

Concrete Path Cost NZ

Concrete paths are often relatively straightforward, but their smaller size does not automatically mean a very low square-metre cost.

There are still setup costs associated with:

Excavation
Base preparation
Boxing
Concrete delivery
Labour
Finishing

A narrow path around the back of a house may also require more manual handling than a much larger open driveway.

This is another reason square-metre prices need to be considered in context.

Concrete Slab Cost NZ

The cost of a concrete slab depends heavily on what the slab will be used for.

Examples include:

Garden sheds
Garages
Workshops
Houses
Commercial buildings
Equipment pads
Warehouse floors

The required specification can change according to:

Slab thickness
Reinforcement
Ground conditions
Foundations
Building loads
Vehicle loads
Machinery
Insulation
Moisture barriers
Engineering requirements

A small utility slab and an engineered workshop slab should therefore not be expected to have the same square-metre cost.

Garage & Shed Concrete Slab Cost

For a new garage or shed, the slab is often part of the overall building foundation rather than simply a flat piece of concrete.

Pricing can be affected by:

Building dimensions
Excavation
Perimeter foundations
Reinforcing
Slab thickness
Door levels
Drainage
Building anchoring
Vehicle loads

If the building will contain a vehicle hoist, heavy machinery or concentrated loads, this should be discussed before the slab is priced and poured.

Making provision during construction is generally much easier than trying to modify an unsuitable slab later.

Concrete Foundation Cost NZ

Foundations are difficult to price using a generic square-metre rate because they depend heavily on the building and engineering design.

Cost factors can include:

Building size
Foundation type
Excavation
Ground conditions
Reinforcing steel
Concrete volume
Formwork
Access
Engineering
Site slope

For house foundations and other structural projects, provide architectural and engineering drawings when requesting pricing wherever possible.

Concrete Retaining Wall Cost

The cost of a concrete retaining wall depends on much more than its visible size.

Important factors can include:

Wall height
Wall length
Excavation
Footings
Reinforcement
Concrete volume
Formwork
Drainage
Backfilling
Site access
Engineering requirements

A retaining wall supporting landscaping has different requirements from a wall supporting a driveway, building or other significant load.

For substantial retaining work, structural design may form part of the project.

Commercial Concrete Cost

Commercial concrete pricing can vary considerably depending on the operational requirements of the site.

Projects may include:

Warehouse floors
Workshop slabs
Commercial driveways
Concrete yards
Loading areas
Hardstands
Car parks
Equipment pads

Concrete used by trucks, forklifts, heavy machinery or high volumes of traffic may require a different specification from ordinary residential concrete.

Commercial quotes should ideally be based on the relevant plans, specifications and expected loads.

How Much Does It Cost to Remove Old Concrete?

Removing existing concrete adds another component to the project price.

The cost depends on:

Concrete thickness
Reinforcement
Total area
Equipment access
Breaking and cutting requirements
Loading
Transport
Disposal

Removing a small unreinforced path is very different from demolishing a large reinforced driveway or commercial slab.

When requesting a quote, make it clear whether existing concrete needs to be removed and disposed of.

Is It Cheaper to Repair or Replace Concrete?

Repair is not always cheaper in the long term.

Minor or isolated damage may be worth repairing.

Replacement may make more sense where there is:

Extensive cracking
Significant settlement
Multiple uneven sections
Poor drainage
Major surface deterioration
An unsuitable existing layout

It is also important to determine why the concrete failed.

If the underlying cause is unstable ground or poor drainage, repairing the visible crack alone may not solve the problem.

Does Concrete Pumping Increase the Cost?

Yes.

Concrete pumping is an additional project cost, but it can make otherwise difficult pours practical.

A pump may be required where there is:

No truck access to the pour
A rear section
A long distance from the road
A steep property
Buildings blocking access
Restricted commercial access

If you’re unsure whether pumping will be required, provide photos showing access when requesting a quote.

Does Project Location Affect Concrete Pricing?

It can.

Pricing may vary across New Zealand because of:

Concrete supply costs
Labour rates
Travel distances
Local material costs
Contractor availability
Pumping availability
Distance to disposal facilities

A project in a major urban centre may therefore price differently from an equivalent job in a remote rural location.

Can I Save Money by Preparing the Site Myself?

Possibly, but it is worth discussing this with the contractor before doing any work.

Concrete relies heavily on correct levels, excavation depth, base material and compaction.

Removing vegetation or clearing easy obstacles may be useful, but incorrectly excavating or preparing the base could create additional work rather than reducing it.

If you want to complete part of the preparation yourself, agree on exactly what is required first.

Is the Cheapest Concrete Quote the Best Option?

Not necessarily.

When comparing concrete quotes, check what each price includes.

One quote may include:

Excavation
Base course
Reinforcement
Concrete
Boxing
Finishing
Removal of waste

Another may exclude several of those items.

Also compare the proposed:

Concrete thickness
Reinforcement
Preparation
Finish
Drainage
Scope of work

A lower headline price is not necessarily cheaper if substantial extras are added later.

What Information Helps Get an Accurate Concrete Quote?

The more useful information you provide, the easier it is to understand the project.

Include:

Your location
Type of project
Approximate dimensions
Photos of the area
Existing surface
Site access
Intended use
Preferred finish
Drainage requirements
Any plans or drawings

For driveways, workshops and commercial projects, also mention what vehicles or machinery will regularly use the concrete.

Concrete Cost FAQs

What is the average cost of concrete per m² in NZ?

There isn’t one reliable rate that covers every concrete project.

For installed concrete driveways, current NZ pricing guides often indicate approximately $100–$200+ per square metre, but preparation, access, thickness, reinforcement and finish can move a project significantly above or below broad online estimates.

How much is exposed aggregate concrete per m²?

Exposed aggregate generally costs more than standard concrete because of the decorative aggregate and additional finishing process.

Actual rates vary by region, aggregate selection, preparation and project size.

What is the cheapest concrete finish?

A straightforward plain or standard concrete finish will generally be cheaper than decorative options such as exposed aggregate or coloured concrete.

Why are small concrete jobs expensive per square metre?

Smaller jobs still involve setup, travel, concrete delivery, preparation, boxing and labour.

Those fixed costs are spread across fewer square metres.

Does concrete thickness change the price?

Yes.

A thicker slab requires more concrete, and heavier-use projects may also require additional reinforcement and preparation.

Does reinforcing increase concrete cost?

Yes.

Reinforcing mesh or steel adds both material and installation costs, although the requirements depend on the individual project.

How much does concrete removal cost?

There is no single rate because removal cost depends on the area, concrete thickness, reinforcement, access, machinery required and disposal.

Should I budget for drainage as well?

Yes, where drainage work is required.

It is better to include suitable drainage when the project is being constructed than discover water problems after the concrete has been completed.

Can I get an accurate concrete price from photos?

Photos and measurements can be very useful for initial pricing, but some projects may require a site visit before the final scope and price can be confirmed.

Online concrete prices are useful for early budgeting, but they cannot account for the exact ground conditions, access, preparation and finish required for your property.

Whether you’re planning a concrete driveway, patio, path, foundation, garage slab, workshop floor, retaining wall or commercial concrete project, the best next step is to get pricing based on the actual job.

Provide your location, approximate dimensions and as much information about the site as possible.
