World Water Day

World Water Day History

World Water aims to stimulate discussion and drive action towards resolving water-related concerns, from lack of access to clean drinking water and sanitation to the intersection of climate and water. The day revives commitment to the ongoing Sustainable Development Goal 6 which is to ensure that everyone everywhere has access to clean drinking water by 2030.

The inception of World Water Day was at the 1992 United Nations Conference on Environment and Development in Rio de Janeiro. For New Zealanders, this day bears particular importance owing to the country’s geographical location and diverse ecosystems. Surrounded by water bodies, with its lush landscapes, rivers and lakes, the country is no stranger to the relevance of individual and collective responsibility towards sustainable water practices. Issues such as freshwater diversity, water quality, cultural values associated with water, and adjustment to climate variability sit at the heart of World Water Day for New Zealand's population.

In New Zealand, World Water Day serves as a platform for communities, non-governmental organizations, and government sectors to foster dialogue and inspire actions around water issues. The observance sees an array of activities including educational forums, exhibitions, and targeted campaigns aimed at raising awareness about water consumption habits and the value of conserving and protecting our fresh water resources. World Water Day takes place every year on March 22nd, marking a universal effort towards preserving the world's most vital life source.
