The Oratia Stream is a stream of the Auckland Region of New Zealand's North Island. It flows north-east from its source at the township of Waiatarua in the Waitākere Ranges, before entering into the Te Wai-o-Pareira / Henderson Creek, which flows into the western the Waitematā Harbour. After beginning at Waiatarua, the stream passes through the rural locality of Oratia and the West Auckland suburbs of Sunnyvale and Henderson. Since the mid-2000s, the Oratia Stream has been forested with native flora.
