Why is mānuka honey rare and expensive?

There are many factors that affect manuka honey yield each season and the conditions have to be 'just-right'.

Mānuka grows in the farthest reaches and isolated parts of New Zealand and can be difficult to access. Hardy and resilient, Manuka can also be difficult to grow. Manuka honey can only be made over a short time frame (around six weeks a year) when the plant is in flower. The amount of honey produced can vary greatly depending on weather conditions and how much nectar is produced. You need dry, warm, summer conditions with moisture in the ground and balmy nights for the nectar of the flowers to start flowing.
