2024 New Zealand Total Diet Study

Have your say

The New Zealand Total Diet Study aims to evaluate the risk to New Zealanders from exposure to certain chemicals such as agricultural chemicals, contaminants, and nutrients in a range of foods most commonly eaten in a typical diet. The 2024 NZTDS will focus on New Zealand infants and toddlers, one of our most vulnerable population groups.

We are seeking feedback on the proposed chemicals selected for monitoring, the proposed key foods list, and overall proposed approach for the 2024 NZTDS.

Consultation opens on Wednesday 15 November and closes at 5pm on Friday 15 December 2023.

What's being proposed?

For the first time, the 2024 NZTDS will focus on New Zealand infants and toddlers, one of our most vulnerable population groups. The study will involve sampling foods most commonly consumed by infants and toddlers (six months to four years of age) and analysing these foods for certain agricultural chemicals, contaminants, nutrients, and other chemicals of interest, for example those from food packaging. We then estimate infants’ and toddlers’ exposure to these chemicals through consumption of foods, and compare this with health-based guidance values to identify if certain chemicals are a concern in the diet.

It is intended that sampling and testing of foods will commence in early 2024 and will continue over a year long period. Results of the study are expected to be published in 2026.
