Brew my own beer here...and distill my own spirits too.....interestingly, distilling spirits for personal consumption in NZ is legal....but you are limited to just 100 litres a month 
 
  
Is that for real?  I'm from the back-end of Northern Ireland originally and can cheerfully inform you that even over there you really had to be pretty decent at crossing Borders and know the 'right' People  to get away with even  a little DIY home fermentation, let alone mass-production on the scale described.  More power to you and May the Force be with You...
