Miller [M] lists this of course (he is a Kiwi), and gives us the gen on the labels name - it stands for To Assist New Zealand Artists. Sure! Tanza was New Zealand's first locally produced gramophone label. Needless to say, indiginous Maori music was featured.  

Speaking of NZ labels, the appropriately named Tasman is another, which existed throm 1949 to 1953.
