Te Ahiaua (The Pipi Beds) is a freedom camping reserve located near the mouth of the Waiotahe River, approximately 8–9 km west of Ōpōtiki on State Highway 2, in the Tairāwhiti Gisborne region.

The site sits close to the broad white sands of Waiotahe Beach, and at low tide visitors can observe locals gathering pipi shellfish along the shore. The reserve offers a shelter, bench seating, and open space for recreation.

Camping is restricted to the signposted area at the eastern end of the reserve. Overnight stays are permitted for self-contained vehicles only — campers must have their own toilet facilities and carry out all rubbish. No drinking water is available on site.

A caravan toilet disposal site is located on SH2 approximately 2 km west. The maximum stay is three consecutive nights, and dogs must be kept under control at all times.
