Nitrates in New Zealand’s Water: The Hidden Health Risk You Should Know About
Share
Across New Zealand, nitrate levels in drinking water have quietly reached alarming levels. In many rural and even semi-urban areas, nitrate concentrations exceed 10 mg/L, a level that’s increasingly linked to serious long-term health risks — including colon cancer and birth complications.
This growing issue highlights why clean, properly filtered water is no longer a luxury , it’s a necessity.
Why Are Nitrate Levels So High?
The primary cause of rising nitrate contamination is intensive agriculture.
Fertilizer (Synthetic Nitrate fertilizer) runoff and animal waste from dairy and livestock farms seep into groundwater and aquifers, the same sources many households rely on for their drinking water.
When rainwater carries these residues into bores, wells and rivers, nitrate levels build up over time. Once present, nitrates are extremely difficult to remove naturally, meaning the problem doesn’t simply go away, it accumulates.
The Health Risks of Nitrates
Nitrates may sound harmless, but inside the body, they can convert into nitrites, which interfere with how oxygen moves through the blood. This is particularly dangerous for infants (known as “blue baby syndrome”) but also concerning for adults.
In recent years, research from New Zealand and Europe has linked high nitrate levels in drinking water to an increased risk of colorectal (colon) cancer - even at levels well below the current New Zealand drinking water standard of 11.3 mg/L.
Put simply: even “legal” levels might not be safe.
Long-term exposure can silently burden your body - affecting energy, digestion, and overall wellbeing.
How to Remove Nitrates from Your Drinking Water
Unfortunately, most standard filters - including carbon or sediment filters cannot completely remove nitrates.
Boiling doesn’t help either; in fact, it can make the concentration worse as water evaporates.
The most effective solution is Reverse Osmosis (RO) filtration.
RO systems push water through a semi-permeable membrane, filtering contaminants down to 0.0001 micron, including nitrates, heavy metals, chlorine, bacteria, and more.
Our RO Mineral+ System takes this one step further.
It not only removes harmful nitrates and other impurities but also re-mineralises the water, restoring natural minerals and producing clean, slightly alkaline, mineral-rich drinking water.
The result is pure, healthy hydration that protects your body from contaminants and supports optimal health every day.
The Takeaway
New Zealand’s nitrate problem isn’t going away any time soon, in fact - it appears to be worsening. With agricultural intensity increasing, protecting your household water supply is the only way to take control of what you drink.
A Reverse Osmosis filtration system gives you that peace of mind, transforming potentially contaminated tap water into safe, revitalizing hydration you can trust.
Because when it comes to your health, clean water should never be compromised.
