Why Organic and GE Cannot Coexist in NZ, why The Gene Technology Bill needs to be scrapped. Genetic modification is sometimes promoted as modern.
A scientific paper assessing the safety of glyphosate, the active ingredient in Roundup, was formally retracted in 2025, 25 years after its publication. The 2000 study had concluded that glyphosate was safe for humans. The retraction followed evidence from court documents released in 2017 showing that company employees had contributed to the paper without being listed as authors — a practice known as ghostwriting. Despite these concerns being publicly known for several years, the journal did not issue a retraction until 2025. Before its withdrawal, the paper was widely cited and relied upon by regulators in assessing glyphosate’s safety. Its retraction highlights the importance of transparency, independence, and caution when research is used to inform public health and environmental policy. What is glyphosate? Glyphosate is the active ingredient in many weedkillers used in NZ, including Roundup. Roundup was originally developed by Monsanto, which has since been acquired by Bayer.

Many scientists warn of Genetic crop health issues and chemical dependance. NZ needs to say no to the Gene Technology an Glyphosate increase bills.

Glyphosate accumulates in human tissues, disrupts gut health and hormones, impairs cognition, and increase the risk of cancers such as non-Hodgkin lymphoma. NZ.
Economic and Sectoral Risks
There are economic risks: The Sustainable Business Council's members collectively represent NZ$169 billion in annual turnover.
These Bills Could Threaten Key Sectors:
If NZ raises glyphosate limits and weakens genetic safety laws, these risks including cancer, neurological, and hormonal impacts will increase, not decrease.
