Independent testing commissioned by No More Glyphosate NZ found low levels of glyphosate in two of five honey products tested. Three samples were below the laboratory reporting limit, while no AMPA or glufosinate was detected in any sample. The results highlight how independent testing helps reveal what is actually present in foods New Zealanders buy.
Flour has been one of the most requested foods in our independent testing programme. Four supermarket flour products were independently tested by Hill Laboratories for glyphosate, AMPA and glufosinate. Three samples returned non-detect glyphosate results, while one contained a measurable residue. This article presents the laboratory findings in full and explains what the results do—and do not—tell us.
We tested three potato varieties purchased from Woolworths New Zealand for glyphosate residues. All three returned non-detect results. Here's what that means—and what it doesn't.
Independent laboratory testing of six Weet-Bix-style breakfast cereal products found four below the laboratory reporting limit, while two Australian-made Sanitarium products returned detectable glyphosate residues — including one result of 3.9 mg/kg.
When Nestlé Cerelac Regular Wheat baby cereal was tested overseas, the result wasn’t dramatic—but it raised a question.

We tested supermarket bread again to see if the first results were a one-off or part of a pattern. What we found wasn’t uniform. Some loaves came back with no detectable glyphosate, while others contained measurable levels from the same shelf. The question now isn’t just what’s there—but why the difference exists.
We independently tested four widely sold Marlborough Sauvignon Blancs for glyphosate and related herbicides. Here’s what the lab results showed — and what “not detected” really means.
Six popular oat products were tested in New Zealand and none showed detectable glyphosate above 0.010 mg/kg. A reassuring result — for these specific batches.
Our fourth round of honey testing shows glyphosate residues in four out of five retail honeys. Levels ranged from a non-detect in Hunt & Gather’s Kānuka honey to the highest result we’ve recorded so far — Wrights Mānuka (Kerikeri) at 146.7 ppb, exceeding New Zealand’s legal limit for honey.
We commissioned independent, accredited lab tests on five popular supermarket breads in September 2025. Three loaves tested clean at trace levels, while two contained measurable glyphosate residues. See the full results and why they matter.
Our third round of honey testing reveals glyphosate residues remain common in New Zealand honey. Six out of seven samples contained detectable traces, and one exceeded the domestic Maximum Residue Limit.
We tested six popular supermarket breads for glyphosate and related chemicals. No residues were found above the reporting limit, but that doesn’t mean they’re glyphosate-free.
