Kwila Decking Tauranga

At DECKHQ, we proudly supply and install Kwila decking timber as part of our deck building projects across Tauranga, Papamoa, Mount Maunganui, and the wider Bay of Plenty. Kwila is one of the most popular hardwoods for decking in New Zealand, renowned for its durability, rich colour, and exceptional resistance to harsh weather conditions.

Kwila Decking Timber Qualities

Kwila, also known as Merbau, is a dense, highly durable hardwood native to Southeast Asia and the Pacific Islands. It is particularly sought-after for outdoor use thanks to its excellent natural resistance to termites, decay, and moisture. Its stunning reddish-brown colour, coupled with a distinctive interlocking grain, creates a warm, premium finish that enhances any outdoor living space.

While Kwila’s durability and aesthetic appeal make it a top choice for decking, the timber does contain natural tannins that may leach during the first few months after installation. This can cause staining on nearby surfaces but quickly reduces with time and weathering. As with all tropical hardwoods, responsible and sustainable sourcing is a priority for DECKHQ, ensuring our Kwila is ethically harvested.
