We have divided the testing results up into three categories:
Testing reports
The annual reports done after each season.

Interactive data
You can explore our testing results data interactively. You can see our results by one substance or a selection of substances. We also produce an interactive visualisation of what substances we have found each year.
Use Shiny App to see our results by substance

These reports are one-offs by KnowYourStuffNZ investigating things like risk perception.
