Whakamana Cannabis Museum, Cannabis museum in Auckland, New Zealand

Whakamana Cannabis Museum is a museum in Auckland, New Zealand, housed in the Hopetoun Alpha heritage building, which has been nicknamed the "Green House". It shares its premises with Calyx Clinic, a legal medicinal dispensary, and displays educational material on cannabis science, history and legislation.

The museum was founded in 2013 by Abe Gray and Julian Crawford, making it the first institution of its kind in New Zealand. Their aim was to shift the public conversation about cannabis away from taboo and toward informed discussion.

Whakamana is a te reo Māori word meaning to give authority or empowerment, chosen to frame the museum as a place of open discussion rather than judgment. The museum operates in a shared space with Calyx Clinic, a legal medicinal cannabis dispensary, and hosts community events for patients, using its premises for community functions. It does not sell cannabis to the public.

The museum occupies Hopetoun Alpha, a heritage building in central Auckland dubbed the "Green House", and shares the space with Calyx Clinic, a legal medicinal dispensary. It is reached on foot from the city centre. Because much of the material is written, allow time to read the panels rather than only look at objects.

The museum regularly hosts discussion groups and community events where visitors can share their own views on drug policy alongside others. This turns the space into something closer to a meeting point than a conventional exhibition room.
