Clear Waters Ahead: Navigating Lead Contamination in New Zealand's Drinking Water

In New Zealand, the issue of lead contamination in drinking water emerges as an unexpected concern. While not as widespread as in some parts of the world, certain areas, particularly those with older plumbing systems, face this hidden threat. Homes equipped with lead pipes or fittings, especially prevalent in parts of the South Island where water tends to be more acidic or corrosive, are at a heightened risk of lead leaching into their drinking water. This reality underscores the importance of vigilance and proactive measures to ensure water safety.


Ionza, attuned to these concerns, champions the importance of testing water for lead, recognizing the potential health hazards that lead poses, such as:


  1. Neurological Impact: Lead is particularly harmful to children's developing brains and nervous systems, leading to reduced IQ, attention span, and academic achievement. In adults, lead exposure can cause memory loss and decrease the ability to concentrate.
  2. Cardiovascular Effects: Lead exposure can increase the risk of hypertension and high blood pressure. Long-term exposure can contribute to heart disease, the leading cause of death worldwide.
  3. Kidney Damage: Lead can accumulate in the kidneys, leading to renal dysfunction. This damage can affect the body's ability to filter waste from the blood, leading to other health issues.
  4. Reproductive Problems: Lead exposure can reduce fertility in both men and women. In pregnant women, it can cause harm to the fetus, leading to low birth weight and premature birth.
  5. Immune System Suppression: Lead exposure can weaken the immune system, making the body more susceptible to infections and illnesses.

Ionza advocates for comprehensive strategies to mitigate these risks.


Addressing lead contamination involves a multi-faceted approach. The first step is getting your household water tested for lead. This initial measure provides a crucial understanding of the water's quality and the specific actions needed. We do sell “17 in 1 Testing strips” which have LEAD as one of the contaminants it tests for, or you can get a fully comprehensive test from your closest laboratory to give you exact levels.  For those who discover lead in their drinking water, several steps can significantly reduce exposure:


Utilizing Water Filters: Investing in a water filter certified to remove lead is a practical and effective way to purify drinking water directly from the tap. Ionza's advanced water filtration systems stand out as a reliable solution, specifically designed to tackle contaminants like lead, ensuring the water's safety and enhancing its health benefits. Call us to ascertain the best solution for your home.


Flushing the Tap: A simple yet effective practice involves flushing the tap for a few minutes before using the water for drinking or cooking. This process helps clear out any stagnant water in the pipes, potentially reducing lead concentration.


Replacing Harmful Components: For a more permanent solution, replacing lead pipes or fittings with safer alternatives eliminates contamination, safeguarding the water supply for the long term.


Ionza's commitment to enhancing water quality extends beyond filtration; it's about integrating health-promoting technologies into everyday life. By offering advanced filtration systems that remove lead and improve the water's alkalinity, pH, and antioxidant levels, Ionza ensures your drinking water supports your optimal well-being.


In a country celebrated for its natural beauty and environmental consciousness, addressing the issue of lead contamination in drinking water with informed, practical solutions reflects a commitment to preserving health and the environment. Ionza stands at the forefront of this mission, providing peace of mind and promoting a healthier, more sustainable future for New Zealand.
