Mt Paku in Tairua is a volcanic peak rising up between the southern end of Tairua Beach and the Tairua harbour mouth. 7-8 million years ago, Paku’s origins as an island volcano commenced with an eruption of ash and pumice. About 6,500 years ago, sea levels rose and allowed the sandspit north of Paku to develop and establish a land bridge, connecting the island volcano to what we now know as Tairua.
