You may want to check the following website www.createyourwoeneden.org.nz for questions/answers regarding Bokashi (composting and wormfarms too) and subsidised or free systems (Bokashi or one of the other options). I got one of the systems for free on the North Shore after attending a three hour long free course on composting systems and pledging to use the provided system. Some other areas of Auckland subsidise systems and I think a few other cities were mentioned on the website too. All in all I would say it was a worthwile activity and I am more than happy with my free wormfarm (I bought my Bokashi bin already 3 years ago).
Kiama (NSW Australia) council apparently subsidises bokashi bins now and Wollongong Council is considering it for the next financial year.... and Wollongong Council is busy running courses now teaching how to create your own bokashi bin cheaply and how to make your own bokashi bran.
