How Much Does Timber Decking Cost in New Zealand?

Building a timber deck is one of the most popular ways to expand living space. With this, you can enjoy the breathtaking outdoor lifestyle of New Zealand. If you maintain your timber deck, you may enhance the comfort and increase the value of your property.

However, it is important to understand the cost before you ask an expert to design your ideal timber deck. Depending on the type of wood and other factors, timber decking costs in New Zealand can vary greatly. Professional or DIY installation for timber decking can also vary in cost.

Well, we are here to examine the price variations between hardwoods and treated pines. By the end, you'll know exactly how much your timber decking job will cost and how to make a sensible budget.

Average Cost of Timber Decking in New Zealand

For a properly fitted timber deck, homeowners in New Zealand should budget between $250 & $500 per square meter on average.

This is a general breakdown of timber decking cost:

• Simple pine decking: $250 to $350 per m²


• Hardwood decking(Kwila, Vitex, Garapa): $350 to $450 per m²


• High-end hardwoods (spotted gum, mahogany, and jarrah): $450 to $500+ per m²

Usually, labour, materials, and basic foundations are included in these costs. However, if you need intricate designs, several floors, balustrades, or built-in elements, the price may increase.

Depending on the type of lumber, material-only prices for DIY projects might range from $80 to $200 per square meter. Professional installation expenses are mostly attributed to labour. So if you have the time and are comfortable with tools, doing it yourself can save thousands of dollars.

Factors That Influence Timber Decking Costs

The ultimate cost of constructing a timber deck depends on several factors:

Type of Timber

• Treated pine: The most affordable, robust, and accessible choice. Ideal for decks with a tight budget.


• Kwila: Well-liked, richly colored, reasonably priced hardwood.


• Vitex and Garapa: Sustainable imports are a little more expensive than pine but require less upkeep.


• Spotted gum and jarrah: They are premium hardwoods that look beautiful and are quite durable.

Deck Size

The cost increases with the size of the deck. Large entertaining areas (50+ m²) can cost more than $20,000, while small decks (10–15 m²) may cost $3,000–$5,000.

Height and Foundations

While higher decks need sturdier foundations, posts, and safety features, decks around ground level are less expensive.

Design Complexity

Simple rectangular decks are reasonably priced. Stairs, curved edges, several levels, and integrated seats all add to the expense and labour time.

Costs of Labour

In New Zealand, professional deck builders usually bill between $50 and $90 per hour. Between 40 and 60 percent of the project budget may be spent on labour.

Consent of the Council

You should budget between $500 and $1,000 for permit fees if your deck calls for consent.

Additional Features

Pergolas, lights, built-in seats, and balustrades all increase usefulness but come at a great timber decking cost.

Additional Costs to Consider

Keep the following possible extras in mind while planning your deck budget:

• Railings and balustrades: $200 to $500 per meter, depending on the material (aluminium, glass, or timber).


• Stairs: $500 to $1,500 for stairs, depending on materials and size.

Budget blowouts later in the project can be avoided by accounting for these expenses up front.

DIY vs. Professional Installation

DIY Decking

• Savings: Only the materials cost $80–$250 per m2.


• Benefits: The overall cost is lower, which is good for experienced do-it-yourselfers.

If you know how to use tools, DIY might be a suitable alternative for tiny, ground-level decks. It is highly advised to choose a licensed builder for larger, higher, or more complicated decks, particularly when council approval is needed.

Tips for Saving Money on Timber Decking

• If cost is your major concern, go with treated pine.


• Rectangular forms are less expensive, so keep your design simple.


• To save money on foundations, build at ground level.


• To save money on expensive delivery costs, source products locally.


• DIY maintenance, like cleaning and oiling, rather than employing experts.


• To prevent costly mid-project design revisions, plan your decking with the experts.
