Abstract: A satisfactory nursery technique for kauri (Agathis australis) has been developed. Current trials aim at streamlining the various phases.
Blood and bone and superphosphate separately have increased the size of nursery stock but the effect on planted kauri is not so apparent.
A kauri seed orchard has been established at Waipoua Forest and others are planned elsewhere in the Auckland Conservancy of the Forest Service.
The most important factor in the planting phase is soil condition rather than nutrient content. Friable well-drained soils of low fertility are preferable to comparatively fertile, normally compacted clays. Early planting (April) is an advantage. A light cover crop is desirable but this must be either entirely removed or drastically reduced within 5 years of planting.
