Hamilton Library has a 3D printing service, have you tried your local library?

The lady told me a key chain would cost about $0.50, which I thought was pretty reasonable.  

Thanks, our library does have one, it doesn't do what I need which is a big bugger.

I need one that prints wood fibres but google search isn't bring anything up.

You could maybe try 3dhubs.com (I haven't used them since they switched from a community of hobbyist printers to a closed list of professional companies). Or possibly makexyz.com

Try the facebook group : NZ 3D PRINTING

or, you'll find some 3d printing services on trademe.
