Piripi Haurangi signed the Waitangi sheet of the Treaty of Waitangi on 6 February 1840 at Waitangi. He was a rangatira (chief) from the Te Uri Taniwha hapū (subtribe) of the Ngāpuhi iwi (tribe).
Piripi sold the Waimate block in the Bay of Islands to the missionary George Clarke for the Anglican Church Missionary Society. The 300-acre (121 ha) block was bought for £167 in cash and £268 in kind, including three horses.
In 1836 and 1837, Piripi signed the sale documents for enclosures 28 and 28a of the Taiamai block in Waimate. These two pieces of land were also sold to Clarke. For no. 28 he paid two blankets, four hatchets, two axes, two hoes, 10 pounds of tobacco and 20 pipes. The 20 acres (8 ha) of no. 28a enclosure cost £2 and two pounds of tobacco.
