Decking Timbers

Q: What is the ideal distance between decking boards?

The ideal gap size between individual decking boards is 1/8 of an inch to 1/4 of an inch. This will allow any water or debris to flow through the gaps while ensuring the surface is flat and safe to walk on. Larger gaps pose a tripping hazard, particularly for smaller children.

Q: What kind of maintenance will my timber decking need?

Experts recommend you maintain your deck at least once a year by cleaning, sanding, and staining the wood. Cleaning more regularly will prevent dirt and mould buildup, which in turn decreases the frequency of staining. Sanding is key to a smooth, splinter-less deck, which is a must for poolsides.

Q: How much timber decking will I need for my project?

The amount of decking you require will depend on the size and scope of your project. Measure out how long and wide you want your decking to be. A general rule of thumb is to determine the surface area in square metres, then divide this number by the width of your selected decking boards.

Q: Do timber decks last a long time?

If maintained properly, timber decks will last an estimated 10 to 15 years. Composite decking can last even longer, from 25 to more than 30 years. This is because of the complex composition of materials that resist decay and damage. It is important to treat your deck regularly to prevent premature ageing.

Different types of decking timbers

There's a great range of different decking timbers available in New Zealand, including many hardwood decking timbers, each with its own qualities and characteristics. The most popular include:

1. Kwila decking

Kwila decking is a durable and attractive hardwood timber native to Southeast Asia and the Pacific Islands.

2. Pine decking

Pine decking is a popular and affordable softwood timber option made from pine trees. While less durable than hardwoods, it can still provide several years of use with proper care. Pine is customisable and widely available, making it attractive for those on a budget or looking for a temporary decking solution.

3. Vitex decking

Vitex decking is a durable hardwood that's ideal for outdoor use, particularly in coastal areas, due to its strength and water-resistant properties. It requires minimal maintenance and can last for several years. Vitex is also sustainable and easy to work with, making it an environmentally friendly choice.

4. Bamboo decking

Bamboo decking comes in various colours and patterns, is easy to install, and requires occasional cleaning and resealing.

5. Garapa decking

Garapa decking is a popular hardwood for outdoor projects, known for its durability, natural colour, and insect resistance. Sustainably harvested in South America, Garapa wood is easy to work with and can last for decades with proper maintenance. It is also less prone to splintering and warping, making it a safe and comfortable option.

6. Purpleheart decking

Purpleheart decking is a dense and durable hardwood known for its striking purple colour. It is naturally resistant to rot and insects, making it suitable for high-traffic areas. Its unique beauty and strength make it a popular choice for outdoor construction.

7. Macrocarpa decking

Macrocarpa decking is a durable and versatile softwood sourced from the Monterey Cypress tree. It offers natural resistance to decay and insects and features a distinctive grain pattern and colouration. Its versatility makes it a popular choice for outdoor construction and custom designs.

Jarrah is a dense hardwood sourced from Western Australia. It features a deep, rich red colour and a distinctive grain pattern, making it a popular choice for high-end outdoor projects.

What are the benefits of high-quality timber decking?

High-quality decking timbers are a smart investment for any New Zealand home, offering durability, style, and long-term value. Designed to withstand the country’s harsh weather conditions — whether it’s intense sun, heavy rain, or salty coastal air — these timbers resist warping, cracking, and decay, keeping your deck looking great for years. They also add natural beauty and warmth to outdoor spaces, creating the perfect spot for entertaining, relaxing, or enjoying the stunning Kiwi landscape. With sustainably sourced options available, you can choose an eco-friendly solution that enhances your home while being kind to the environment.

How to choose the right decking timbers for your home

Choosing the right decking timbers for your New Zealand home comes down to durability, aesthetics, and maintenance needs. Consider the climate in your area — if you’re in a coastal or high-rainfall region, prioritise hardwood decking like kwila or vitex, which resist moisture and decay. Pine, especially when treated or thermally modified, is an affordable and versatile option that performs well in most conditions. Think about the look you want — rich, dark hardwoods add a premium feel, while lighter timbers create a more modern, relaxed vibe. Finally, factor in maintenance; some timbers require regular oiling or staining, while others weather naturally, so choose one that suits your lifestyle and upkeep preferences.

Other decking products to think about

You'll need a variety of products to complete any decking project like decking foundations and decking treatments so be sure to consider these and factor them into the cost of your project. Before making a final decision, you might also want to look at composite decking which is very popular in New Zealand thanks to its organic appearance and synthetic strength.

What is the average thickness of timber decking?

The standard thickness for timber decking boards in New Zealand is about 1 inch thick. For home builders, this is the ideal decking thickness, while commercial areas may require greater deck board thickness. Greater thickness can sustain greater loads, which is good for regions with higher foot traffic.
