While there are no rules about what combinations of materials to use when it comes to designing your own spells, this list of associations and properties is designed to offer inspiration and guidance when making your design decisions. These are extremely brief notes and there is plenty of more detailed information out there online, but if you're looking for a short and simple list to give you some ideas, here it is!
COLOURS
No matter your material, colour can have a major effect on the spell being cast. Colours bring both positive and negative influences to spells, and can be used to guide a result in a favourable direction, or offset an unwanted effect of a material being used. Meanings and interpretations of colour can vary from culture to culture, and as such different characters may also have different reasons for choosing different colours to use in their spellcraft.

WOODS
Due to biosecurity laws and limits on imports, the kinds of readily available wood in Aotearoa are likely not going to be the kinds of wood people in the rest of the world are used to encountering. While this is not an exhaustive list of available wood types, the selection of available options is largely limited by what can legally be grown locally, and I strongly encourage you to double check availability before incorporating a specific kind of wood into your spells.

OTHER
These are materials that while not fitting easily into any of the above categories may be of significant use in spell construction or are otherwise notable. If you think of any additional components that would be a worthwhile or interesting addition to this list, please drop me a message!
Animal Products (Feathers etc.)
Clay
Coal/Charcoal
Glass
Leather
Oil
Paint
Paper/Cardboard
Plastic
Resin
Note: Aotearoa has a strict nuclear free policy, and as such any spells using radioactive components are illegal within the country and can only be used/developed outside of it.
A final note on biosecurity
As an island nation with a unique and fragile ecosystem, plant and animal imports into Aotearoa are extremely strictly regulated. I would advise double checking whether an animal/plant is available within the country before using it in spell design.
