Thought you may want to know that Yeehaa (http://www.yeehaa.co.nz/form.html
) in Auckland stocks Cal's, as well as their own teflon-based drag grease, which is similar, though slightly more viscous.
It's NZ$20 for a pot, which seems pricey, but I've done about 20 reels and am just over 1/3 the way through...
Also, Dawn at Smooth Drag (http://www.smoothdrag.com/
) is excellent to deal with and it actually works out cheaper than the above option, despite the exchange rate, postage etc.
