Nau mai, haere mai.

There is no denying that going to the supermarket has been an increasingly painful process for many New Zealanders. Think about the last time you spent $50 at your local store. Your trolley probably contained no more than a few basic items – and probably much less than ten years ago. It is clear to anyone who does the grocery shop that the price of food has been on the rise.

But as new research from Puneet Vatsa and Alan Renwick reveals, price increases have not been consistent across food categories. Since 2014, fruits and vegetables have increased by 45% while sweet processed foods have increased by just 14%.

This means processed sweet foods have remained, by and large, more affordable than fresh produce.

As the authors note, “New Zealand’s price inflation was greater and has remained more persistent than in many other developed countries, suggesting unique factors may be at play”.

And this is not just hurting our wallets. The fact that processed foods are seeing smaller price increases than fruit and vegetables means the former is an easier choice for struggling families – to the detriment of their overall health.

As the authors point out, the solution to this issue needs to be multi-pronged and include education, subsidies on healthy food and a tax on more processed options.

Many thanks for reading and until next week, mā te wā.
