The primary focus of the New Zealand Total Diet Study (NZTDS) is to assess the exposure of age-sex groups to chemical residues, contaminant elements and selected nutrients. The development of simulated diets for different age-sex groups within the New Zealand population is required so that dietary exposures can be calculated. Given all the key features of the 2009 NZTDS are closely aligned to the 2003/04 NZTDS the simulated diets developed for the 2003/04 NZTDS were recommended for use for the 2009 NZTDS.
