Seasonal fruit and vegetables taste better due to being naturally sun ripened, are fresher and have a higher nutritional value due to less storage and shorter times from harvest to consumption. Knowing what is actually 'in season' is difficult given importing abilities meaning some items with shorter seasons are now available all year round.
The list below is indicative of main seasons for New Zealand when items should be most plentiful (season depending), with the following guides;
*Year round availability due to different varieties with different harvest times
