Is New Zealand an established, international wood exporter?

  • Forestry is New Zealand's largest industry after dairy and meat products, with annual exports exceeding NZ $3 billion.
  • Although only approximately five percent of global timber supply comes from sustainably managed, plantation forests, New Zealand wood exports are a highly sustainable industry. Specifically, 90 percent of New Zealand's 1.7 million hectares of sustainably managed, renewable plantation forest is planted in New Zealand pine.

What is New Zealand Pine?

  • New Zealand Pine is a species of pine called Radiata, also known as Monteray or Insignis Pine.

What is Radiata Pine?

  • Radiata Pine is a fast-maturing and adaptive softwood native to the United States.
  • Since its introduction in New Zealand in the 1950s, it has become a popular softwood throughout the Southern Hemisphere, with significant concentrations in New Zealand, Australia, Chile, and South Africa.
  • New Zealand and Chile lead in Radiata growth with about 2 million hectares (5 million acres) of plantation forests, with large logs of up to 80cm diameter and growing cycles of 25 to 30 years.
  • Commercial cultivation also extends to countries such as as Spain, France, Argentina, Greece, and India. Ironically, it has since become a threatened species in the coastal region of central California from which it originated.
  • Selective breeding practices began in New Zealand in the 1960s and have since advanced the growth and form characteristics of native Radiata. Today the focus of such programmes is on specific traits such as disease resistance and straight grain.
  • Radiata is now a common and accepted replacement for the more expensive pines, such as Ponderosa and Douglas fir, grown in the United States and Japan.

How versatile is Radiata Pine?

  • Radiata is appreciated for its wide range of applications. While obviously suitable for lower grade applications including construction, panelling, pulp/paper products, pulpwood, fibre board, MDF, and plywood veneers, it is also being utilised as a higher grade timber for furniture, veneers, and mouldings.
  • The expanding range of uses of Radiata also stems from new technological processes. For instance, a process developed by Forest Research is used to harden Radiata, making it suitable for flooring and furniture. Also, new lamination and finger-jointing technologies are expanding the uses of Radiata, ranging from small mouldings to vast engineered beams.

What is the appearance of Radiata?

  • Radiata timber is generally straight grained. Its sapwood is pale coloured, while the heartwood is generally pinky-brown. It is unique in its uniform density, meaning that there is little contrast in the appearance of the growth rings relative to other pines. This gives Radiata a relatively even and uniform texture and thus excellent machining, painting, and staining properties. It also has good qualities for accepting a wide variety of paints.

What is meant by 'environmentally sustainable'?

  • New Zealand forests are naturally renewable. They are recyclable and ultimately biodegradable, and they sequester carbon. Since half the weight of timber is carbon, derived from carbon dioxide in the atmosphere, New Zealand forests reduce one of the main gases associated with global warming.
  • While Radiata is grown in plantation forests where it responds well to intensive management, it is also environmentally sustainable.
  • Sustainability refers to the ability of a forest to provide for today's needs without compromising the land's ability to provide for future generations. Radiata Pine grows faster in New Zealand than anywhere in the world, making it especially sustainable here.
  • Radiata's sustainability also stems from its high capacity to adapt to diverse site conditions.
