The Waitangi treaty was signed here in 1840 between maori chiefs and the British crown. The first thinking that the crown would protect their land, the latter not quite thinking along the same lines.
Anyway - the Waitangi treaty is important and referred to still as "The birthplace of our nation, a place all New Zealanderes belong to and where our people advance together." An interesting place. Website: www.waitangi.net.nz
