Medicinal cannabis advocates will be rallying and hosting an art installation in Auckland's Aotea Square this afternoon.
They want a temporary ban on arrests for using the product, and are calling for the Government to take action instead of letting patients suffer.
Auckland Patients' Group convener Pearl Schombury says it's about drawing attention to the plight of patients.
"Law change is not going to happen overnight, but a moratorium can… and that would alleviate the stress and suffering of patients instantly."

Supporters are encouraged to bring a decorated pot representing a medicinal cannabis patient or someone who died.
"We're just hoping many patients and supporters will come along… honouring or commemorating loved ones," says Ms Schombury.

She says people still fear the knock on the door.
"A moratorium, until law change, would actually create a lot of really useful data on how patients are doing."
The gathering begins at 2pm.
