Tiroa Station and its sister lands, Te Hape and Waipa, form the largest continuous area of farm land in the Waitomo district.

Tiroa, Wharekiri and Te Hape make up the largest continuous area farmed by one entity in the Waitomo district.  Located 500m above sea level, it contains the head waters of three major awa: Waipa, Waimiha and the Mokau River, native bush under Nga Whenua Rahui covenant, as well as maturing stands of Radiata pine.

There are a significant number of sacred sites within the boundaries, including Te Hape and Miringa Te Karaka Marae.

The land was originally surveyed in the late 1890s, with cutting rights to mill rimu, totara and matai until the mid-1960s.  By the late 1950s Te Hape was developed by the Department of Maori Affairs and then handed back to the owners in 1974.

The day-to-day management of the farms has always been carried out by experienced and skilled farm managers, some of whom have been in position for a number of years.

Today Tiroa E and Te Hape B Trusts are economically strong enough to pay its shareholders dividends at 30 per cent of net profit after tax.  In addition, grants are offered for tangihanga and to eight marae whose affiliation whakapapa to Rereahu. Interest from unclaimed dividends goes toward education grants.

Tiroa E and Te Hape B Trusts have also embarked on a diversification strategy involving interests in Malaysia, the United Arab Emirates, China and Taiwan.
