Pure One is drawn from a deep artesian aquifer within the Matemateāonga Formation beneath Taranaki, New Zealand.

Over thousands of years, the water has travelled through layers of ancient rock and sediment, acquiring its naturally occurring mineral composition and distinctive taste.

Independent radiocarbon analysis has measured the water at at least 46,000 years old when bottled.

Total Dissolved Solids (TDS) measures the concentration of naturally occurring dissolved minerals and salts in water and is used to classify water according to its level of mineralisation.

In New Zealand:

Mineral water: 250 mg/L TDS or higher

Spring water: less than 250 mg/L TDS

Pure One has a TDS of 790 mg/L, classifying it as a medium-mineral water.

Its naturally occurring mineral composition contributes to Pure One's distinctive character, soft texture and smooth finish.

Pure One is a naturally occurring mineral water with a distinctive sodium-bicarbonate mineral profile and a TDS of 790 mg/L.

Drawn from a deep artesian aquifer within the Matemateāonga Formation beneath Taranaki, the water has been naturally filtered through layers of ancient rock and sediment over thousands of years.

Independent radiocarbon analysis has measured Pure One at at least 46,000 years old when bottled.

Its naturally high levels of sodium and bicarbonate, alongside low concentrations of calcium and magnesium, contribute to its soft texture and smooth finish.

Pure One’s taste is shaped by nature. As the water filters through mineral-rich rock layers deep underground, it naturally absorbs essential minerals that create its distinctive composition.

The result is a soft, refined taste with a clean, smooth finish.

Our minerals include:

• Calcium (Ca)
• Magnesium (Mg)
• Sodium (Na)
• Potassium (K)
• Phosphorius (P)
• Chloride (CI-)
• Iron (Fe)
• Zinc (Zn)
• Colbalt (Co)
• Copper (Cu)
• Manganese (Mn)
• Molybdenum (Mo)
• Iodine (I)
• Selenium (Se)
• Boron (B)
• Vanadium (Va)
• Chromium (Cr)

We reach the aquifer through the Bonithon No-1 Well; a deep, 1,000m sealed well that was originally drilled in 1906 in the hopes of finding oil, however, they discovered warm mineral water instead.

As the aquifer is artesian, this means that the water flows naturally to the surface without the need for any heavy machinery that could be damaging to the earth.

Pure One has been scientifically assessed as being at least 46,000 years old, making it the oldest known mineral water in New Zealand.

Scientists at GNS Science (a New Zealand Crown Research Institute), are able to depict the age of our water through carbon isotope testing. 

'We know your water sample is at least 46,000 years old, but it could be much, much older than that - it was too old to be measured by radiocarbon with any accuracy.'

We recommend enjoying Pure One within 3–4 months.

We recommend keeping your bottles & containers away from the sunlight as best as possible. Always try to store your water containers in a cool, shaded place.

Pure One is tested regularly and complies with the New Zealand Health Regulations, National Program level 3: Manufactures of non-alcoholic beverages/water, to ensure the highest quality.

Pure One undergoes ozonation as part of our standard bottling process to ensure the quality and microbiological integrity of the water before it is bottled at source.

Ozonation is a water treatment process that uses ozone (O₃), a highly reactive form of oxygen. It allows us to treat the water without adding chlorine or other chemical disinfectants and does not alter Pure One’s naturally occurring mineral composition.

Following treatment, ozone naturally breaks down into oxygen, leaving Pure One’s distinctive mineral profile unchanged.

Due to our higher Total Dissolved Solids (TDS) level, we recommend cleaning your containers and bottles regularly to help prevent mineral build-up.

How often?

Every 4 weeks or sooner.

How to clean:

• Use Milton Sterilising Tablets (available at most supermarkets), or
  
• Use white vinegar and warm/hot water
  

Vinegar method:

• Add approximately ¼ cup of white vinegar to your container
• Fill with warm/hot water
• Shake for 30 seconds and allow it to sit before rinsing
  

If your container has a tap, we recommend removing it and cleaning it separately.
