Abstract: Isomagnetic charts of D, H and I are shown for New Zealand at epoch 1950.5. Vertical earth-air electric currents were evaluated and the mutual consistency of the D and H charts were tested using Chapman's criteria. The values of D, H and I are shown for the outlying islands, the Snares, Auckland Islands, Campbell Island and Chatham Islands. (auth)
