Registration Category: Historic tree/s – Local interest
General Notes:
Prominent Oak on the sea shore of Ōhinetahi
A garden was first made on this site in 1865 by T.H.Potts, New Zealand's first botanist. Potts planted a great variety of exotic trees and shrubs, many of which still stand on the perimeter of the garden. He died in 1888 and thereafter the garden fell into dis-repair until it consisted of little more than a lawn around the house.

Sir Miles Warren and Mr and Mrs Trengrove restored the house and began the present garden in 1977. Designed by two architects and an artist, the garden inevitably has a strong frame. The formal garden consists of a number of separate garden rooms of differing style and character arranged about two axis, one running east west and another north south.
