Hi Rach! Welcome to Steemit from a fellow kiwi. Hive account@sift666 and I are the Weston A Price chapter leaders for Wellington so I've made many a batch of kombucha. I haven't got any at the moment, but have milk kefir grains and caspian sea yoghurt if you ever need any starters. My specialty is recipes for people on special diets, which you might find of interest. Another kiwi whose blog you might like is Hive account@ecentrally and there are a bunch more on this post - https://steemit.com/steemit/@sift666/how-many-kiwis-are-here-on-steemit - though I have find more since then. Hope to talk again soon.
