This report summarises the results of palynological study of samples from the Ohai Coalfield (Southland Coal Region) and the Wairaki Hills, an area to the north of the coalfield. In the Ohai Coalfield, Late Cretaceous (Zone PM2) and Middle to Late Eocene (Nothofagus flemingii zone and Nothofagus matauraensis Zone) palynofloras were examined from drillholes 343, 352, 364, 371-379, 381, 882-886, and from Nightcaps Mine, Ohai No. 6 Opencast Mine, and outcrop. Two small outliers of Late Cretaceous sediments in the Wairaki Hills, probably correlative with the Ohai Group, are reported for the first time.
