Just a random guy passing by :p Probably you should find a local Japanese-tool dealer as I presume that you are living in NZ. (?) Or you may order it online by googling "Japanese hand plane / kanna", even ordering straight from Japan by googling "大工道具 鉋” as there are quite a few Japanese shops providing services for overseas customers. Still, if you were to be crazy enough, flying straight to Osaka, please search "大工道具や” with google map. Some manufacturers of quality are located near Osaka, Miki City(三木市). But I hate to tell you that Japanese woodworking tools, unlike ones of Veritas etc., need a bit of love as well as study to make them work. If I should be a hobbyist, I would prefer staying away from them, especially when they are not essentially superior.
