Kamahi honey has traditionally been one of New Zealand's most under rated honeys. While it is produced in both the North and South Islands, most Kamahi honey is produced on the West Coast of the South Island. Here Kamahi trees (Weinmannia racemosa) form a significant part of the forest canopy, growing to around 25 metres at maturity. As Kamahi grows throughout New Zealand other competing nectar sources (and their contribution to nectar composition) vary from location to location. For example North island Kamahi can be produced at the same time as Rewarewa and Manuka so Kamahi from this region can tend to be darker because of the influence of these two darker nectar sources.
