One source. One story.
Mount Taranaki is where our story begins. Rainfall gathers and begins a slow descent deep beneath the earth’s surface - moving through layers of volcanic rock. The water is shaped over time, naturally filtered and protected.
An ancient source
Pure One is drawn from the Matemateāonga Formation - an ancient artesian aquifer beneath Mount Taranaki's volcanic landscape.
Formed between 3.6 and 23 million years ago, this natural system allows water to move slowly through layers of rock - absorbing minerals over time.
As it interacts with the surrounding geology, a distinct mineral profile is shaped by nature.
Under natural pressure, the water rises through a 1,000 metre sealed well.
Carbon dating confirms an age of at least 46,000 years at bottling.
Mineral composition
With 780 mg/L of Total Dissolved Solids, Pure One sits within the medium mineral category, delivering a smooth, balanced taste.
Defined by a dominant sodium-bicarbonate profile and supported by naturally occurring trace elements, its composition reflects its origin.
The result is soft, refined, with a clean, smooth finish.
