"I always compare prices online and you can get things for half the price or a third of the price overseas that you get here."
In the UK, she bought a lot of organic food, but cannot afford to do the same here.
An added difficulty is that Kiwi prices vary markedly with the seasons, making it hard to budget. "In winter, you might get an avocado for $2 but in summer you might get two or three for $1. That doesn't happen in the UK ... consumers would be outraged if prices fluctuated there like they do here."
Her supermarket shopping costs about twice as much here as it did in the UK - something she had not been prepared for. "I'm astounded at how much food has gone up in price since we last visited New Zealand."
She said some of the difference might be due to the large supermarket chains' buying power being bigger in countries where there was a bigger population base, but that did not explain the extent of the difference.
