NZAA site W21/11 (New Zealand Heritage List no. 6510) is a pit complex in pasture on the east side of the Maraetotara River off Clifton Road, Clifton. There are a number of these pit/terrace sites on the uplifted marine terraces through which the Maraetotara River flows. The presence of these pits indicates that the area was extensively used for horticulture. The pits are predominantly of the raised rim variety. The pit/terrace site is of cultural, traditional, archaeological and historical significance.

Archaeological evidence and Maori oral history points to the settlement of Hawke’s Bay around 1250–1300 AD. Different hapu gradually settled the area from Mahia to Porangahau in a variety of different landscapes from the coast to the inland forests. Access to these inland areas was often via rivers like the Maraetotara. The tangata whenua of the Te Awanga (Clifton) area can trace permanent occupation back to the Te Kakano or archaic period of Polynesian settlement. Isolated pockets of Kupe people settled along the Wairarapa coast and came into contact with the descendant of Whatonga who had migrated south from Mahia. Whatonga’s son Tara was born at Te Awanga and is the ancestor for Ngai Tara.

The sites in the area are associated with the descendants of Te Aomatarahi. Mahangapuhua, a son of Whiringarakau, established a pa called Te Pa o Mahanga at Te Awanga. Tama-ariki and Hine-te-ao also occupied this area. Later the area was under the influence of Te Whatui-a-piti through his son Hikawera. Through strategic marriage of the descendants of Ngati Kahungunu, Te Whatui-a-piti and Te Aomatarahi merged the people into the hapu of today. The main hapu interests in Te Awanga are Ngati Kurukuru, Ngati Hikatoa, Ngati Whakaiti, Ngati Ura ki te ao and Ngati Hawea.

While pit complex W21/11 is not rare in this area, the pit and terrace site reflects the importance of horticultural production (kumara) to sustain tangata whenua in this archaeologically rich setting inland of Cape Kidnappers / Mataupo Maui. The terraces of this area provided fertile, flat land on which to grow crops which were then stored in these raised rim pits.

The group of eight very large raised rim pits is on a triangular terrace adjacent to the river. The pits range in size between 4 x 2 metres to about 7 x 5 metres and are all over 1 metre in depth. The pits and the terrace are in excellent condition with up to 1 metre high very well preserved pit rims. It is a likely that the pits are a remnant of a village/kainga site. At this point in time the location has not been identified with a specific Maori name.

The site is in good condition with some pits under trees. A farm track runs part way through the site, but has avoided all visible features and done relatively little damage. In 2015 trees were removed from the site.
