Otumoana, Urenui River, Taranaki

The steep-sided, narrow ridge is defended by ditches, steepened scarps, banks and palisades (no longer showing) constructed across the ridge, often taking advantage of the naturally steep slopes. The pā may originally have been defended only by ditch, bank and palisade across the ridge. The pā lies in three main segments (O, M, K, on the interpretative figure, following Elsdon Best's illustration in The Pa Maori), divided by the two clear transverse ditches and banks. At some time after the initial defences were created, a ditch and/or artificially steepened scarp were created along the side of the ridge (showing on the west of platform 'O'). These connected with the defences running across the ridge.
