46,000-Year-Old Mineral Water

Our story starts as rainfall, high above the Mount Taranaki, surrounded by rich, bio-diverse native bush, pristine streams and waterfalls. As the water slowly begins its 46,000-year voyage deep beneath the earth, it is naturally filtered through layers of volcanic rock; protected and preserved from external elements, untouched by man.

A Unique Single Source Deep Beneath The Earth

Deep beneath the earth lies an ancient artesian aquifer; The Matemateāonga Formation. Late Miocene to early Pliocene in age (3.6 - 11.6 million years), it is recognised as one of the oldest aquifers in New Zealand.

Once the water reaches the aquifer it slowly migrates through reacting with the sediment; ions are exchanged between the water and rock resulting in Pure One's unique mineral content.

The aquifer exists under such geological pressure that the water flows naturally to the surface through a 1,000m sealed well - a true artesian source. With a measured age at bottling of at least 46,000 years, Pure One is assessed as the oldest and deepest known mineral water in New Zealand.

Incredible Minerality

To be mineral water, water must contain at least 250 mg/L TDS (Total Dissolved Solids); anything under that amount results in the water being spring water.


With 780 mg/L TDS, Pure One is the only known mineral water of its kind in New Zealand. Our water includes 17 of the 21 minerals considered essential for health. These include calcium, magnesium, sodium, potassium, phosphorus and chloride. As well as hard to source trace minerals such as iodine, selenium, vanadium and zinc.
