What Ernslaw One does

Ernslaw One is a vertically integrated softwood plantation company headquartered in Auckland, New Zealand, and a subsidiary of the privately held Oregon Group. Founded in 1990, it manages over 95,000 hectares of radiata pine and Douglas-fir across both the North and South Islands, making it the fourth-largest forest estate in New Zealand. Operations span the full forestry cycle from a 14.7-hectare seed orchard and an annual planting programme of approximately two million seedlings, through silviculture (pruning and thinning), mechanised harvesting of approximately 1.4 million tonnes per year, and export logistics. The company is FSC-C010424 certified and operates specialised divisions including the KEEWAI freshwater crayfish aquaculture business across roughly 2,000 ponds in 11 forests, a genetic improvement programme, and an early carbon credit business that completed the first international AAU sale by a New Zealand company in 2009.

The business model is centred on the sale of premium quality softwood logs (sawlog, pruned log, roundwood) to a base of long-tenured domestic sawmills (e.g., Kiwi Lumber, MitchPine, Stuarts Timber, East Coast Lumber) and international export customers in the USA and Europe, with a specialised in-house export team managing shipping. Ancillary revenue is generated from seed and seedling sales to other forestry nurseries, carbon credit transactions, and the KEEWAI aquaculture product line. Distribution relies on direct enterprise sales relationships combined with a logistics chain that, as of January 2025, integrates KiwiRail rail haulage from the Karioi Forest through Napier Port alongside contracted road cartage by McCarthy Transport. Technology assets include custom silviculture growth models, e-DNA environmental DNA sampling for aquatic species monitoring, and a Douglas-fir seed orchard with five grafted families; the company does not operate an API, public software platform, or disclosed AI/ML capability.

Customers are concentrated in the NZ and international softwood lumber supply chain, with sales-led GTM built on long-term relationships, FSC-certified sustainability credentials, and reliable multi-modal delivery. Headcount is reported at 51-100 employees with over 165 contractors supporting the East Coast operation, and leadership under CEO Darren Mann (appointed July 2021) is drawn from deep NZ forestry industry backgrounds.
