New Zealand's Food Safety Agency is promoting the use of iodized salt, according to an article in TVNZ.

"Nutrition programme manager David Roberts says iodine is an essential nutrient for growth and development, however iodine deficiency is re-emerging as a population-wide health problem because New Zealanders aren't getting enough of it in their diet.

"'Because iodine can't be made in the body we need to get it from the food we eat,' he says. 'Iodine supports normal growth and development in children and helps to maintain the body's metabolic rate.'

Iodine deficiency in New Zealand is being addressed through a variety of measures, including requiring bakers to replace non-iodised salt with iodised salt in most bread since September last year."
