One source. One story.
Standing high above sea level and surrounded by lush native forests, pristine streams, and waterfalls, Mount Taranaki is where our story begins. As clouds gather and rain falls, it embarks on a journey deep beneath the earth’s surface. Along the way, the water is naturally filtered through layers of volcanic rock, ensuring it remains protected and pure, untouched by external elements.
An ancient source, untouched
Pure One rests within the Matemateāonga Formation - an ancient artesian aquifer beneath Mount Taranaki. Formed during the Miocene to Pliocene epoch (approximately 3.6 to 23 million years ago), the formation is composed of sandy mudstones, siltstones, and irregular layers of sandstone and limestone.
Over time, water moves slowly through these sediments, interacting with the surrounding rock. Through natural ion exchange, minerals are absorbed into the water, shaping Pure One’s distinct mineral profile.
Existing under such geological pressure the water rises naturally to the surface through a 1,000m sealed well, emerging pure and untouched.
Carbon dating confirms a measured age at bottling of at least 46,000 years, placing Pure One among the world’s oldest assessed mineral waters.
Incredible minerality
Mineral water classification requires a minimum of 250 mg/L of Total Dissolved Solids (TDS). Pure One contains 780 mg/L, placing us within the medium mineral water category.
Our mineral structure is defined by a dominant bicarbonate profile, balanced by sodium and supported by naturally occurring trace elements. Pure One also contains 17 of the 21 essential minerals required for human health.

Notes & classification
Typical analysis at source. Mineral composition may vary slightly due to the water’s natural origin.
May not be suitable for individuals requiring low sodium intake.
Unmistakable taste
Every natural mineral water carries the imprint of its origin. Like fine wine, it has a terroir - a unique environment that shapes its mineral signature and defines its character.
Pure One has rested deep beneath Taranaki for at least 46,000 years - time and geology shaping its distinctive mineral balance.
Awarded Gold in 2024 and 2025 at the Taste & Design Awards, Pure One stands among the world’s recognised waters.
