Our business is currently awaiting an Amendment Bill to be passed and a permit from the Ministry of Health to be granted. Our intention is to raise capital that will be used to complete our facilities located at a hydro power station in order to prepare ourselves for the large waiting market of buyers here in New Zealand. The market for medicinal marijuana products in New Zealand is huge, and across the globe, that market is expected to be worth USD 55.8 billion by 2025. We are investigating our funding options and will update our community as soon as we decide how we will proceed. If you would like to speak to us directly about an investment please get in touch.
