New Zealand Macrocarpa posts are a popular choice for fencing, pergolas, and landscaping due to their natural durability and aesthetic appeal. The heartwood is rated as moderately durable (Durability Class 3), with a 50×50 mm stake lasting 10-15 years in-ground, while larger sections can endure 20-30 years above ground—or up to 40-50 years if sheltered from direct exposure to rain and sun. Unlike treated radiata pine, Macrocarpa does not require chemical preservatives like CCA (copper, chromium, and arsenic) to achieve this longevity, making it an environmentally friendly option for in-ground use when sealed properly (e.g., with a bitumen membrane). Its warm golden-brown hue and natural grain enhance the visual appeal of outdoor structures, giving them a rustic, timeless charm.
