This is crazy - NZ is renowned for having a high percentage of obese people, so how do they expect people to do anything about it when things like milk, meat, poultry, fish, tomatoes & bananas, some of the most basic healthy foods, are going up in price - it's not exactly encouraging the population to eat more healthily
Granted, it's still cheaper to buy fresh food and prepare it at home, than it is to buy takeaway or processed junk, but increasing the price of healthy stuff is unlikely to inspire more healthy eating.
