Isomagnetic maps of eastern New Guinea and the surrounding region are presented showing five magnetic elements reduced to the epoch 1957.5. All magnetic observations made in the region since 1917 have been used; the older observations have been corrected for secular variation by repeat observations at Port Moresby.
