My name is Nick and no, I'm not a luthier, but just a person with too much spare time

I started working on some of my own bass guitar projects. Just for fun, I reckon for the moment. So far I've made two bodies made from kauri and epoxy resin. Again, that's for fun only and I'm not sure about any sonic properties of this wood.
Now I want to try to make my own necks and as far I know it must be maple and probably mahogany or rosewood for the fingerboard. So my question is can you recommend a supplier that can supply small quantities of these woods preferably close to Auckland.
I'm also keen to try a body wit some other woods I know are used for making solid bodies - ash, alder, etc.
Your input will be very much appreciated.
Cheers!
