If you are unsure when a Vegetable or fruit is in Season you can check on this website:
https://www.produce.co.nz/seasonality-chart/
Or if it is not on that list you can google the name followed by “NZ Season”.
If you would like to use a Vegetable which is out of season it may be available in the Frozen Section of the Supermarket, for example, Spinach and Mango.
