New Zealand's Second Meteorite: Makarewa (find, L4, S5, W2)
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.One of the most remarkable discoveries of a meteorite in New Zealand was that of Makarewa. Discovered in 1879, Makarewa is a ‘find’ that was uncovered a metre below the surface of a clay bank during excavation works for a train line in the southern South Island.
