Ōhinetahi valley at the head of Whakaraupō (Lyttelton) harbour, was once the site of a heavily stockade Ngāti Māmoe pā that was stormed by Te Rakiwhakaputa of Ngāi Tahu around 300 years ago. After its capture, Te Rakiwhakaputa’s son Manuhiri occupied the pā with a party of Ngāi Tahu. Manuhiri fathered many sons but only one daughter. He named the pā after his solitary daughter. Ōhinetahi means The Place of One Daughter.

Christchurch Earthquake severely damages the house with stone surrounding four attic gables crashing through the roof and ceiling of the library, cloak room, green room and laundry. The north face stone wall of the drawing room and bedrooms were cracked and bowed out by 100mm. Following this damage, the house was emptied of its artwork and treasures. Third story was removed prior to restoration work was undertaken.


House came through the February earthquake relatively unscathed due to the removal of the stone third story following the September 2010 quake. This action probably saved the property.

Mark Chandler hired as new gardener.

12-month long restoration, repair and strengthening of homestead undertaken. Homestead reconfigured as a more modest and less imposing two-story structure, with the upper story being replaced with a lightweight timber structure with a lower roof line. All the stone constructions within the gardens, walls, towers and follies have been restored.


Sir Miles Warren donated Ōhinetahi to the nation, creating a charitable trust to manage the property.

This place was named by Manuhiri, son of Te Rakiwhakaputa of the Ngāi Tahu iwi. Father to many sons, he had just one precious daughter. Ōhinetahi means ‘place of a single daughter’.

The site’s first European owner, Christopher Alderson Calvert, had a pre-fabricated cottage erected in the early 1850s, called Rosemary Cottage after Bishop Selwyn’s daughter. After consulting local Maori, Calvert adopted the name Ōhinetahi for the wider property.

A few changes of hands later, in 1858, one of New Zealand’s first botanists bought the place: Mr. Thomas H Potts. He subsequently added 317 acres to his original 225 acre purchase. It was Potts who established Ōhinetahi’s gardens and built the sandstone homestead as a large insert between the two halves of Rosemary Cottage.

Alongside a vegetable garden and orchard Potts planted trees, including araucarias, ashes, blue gums, conifers, oaks, poplars, sycamores and walnuts. Although some of the original trees survive, after his death in 1888 the garden was neglected until just the lawn surrounding the house survived.

That was all to change after 1976, when Sir Miles Warren, his sister Pauline and her husband John Trengrove bought the property. After restoring the ramshackle house, the three set about establishing a grand garden. “For John and I the pleasure was to design something as amateurs, not professionals,” said Sir Miles in a 2013 interview. “If we stuffed up, it didn’t matter. We’d simply change it, or replant it, or reorganise. That period, we were both very busy professionally, so it was great relief, moving bricks and removing trees, fighting our way through the jungle and so on. It was an ideal contrast to the working week.”

A respected artist, Pauline Trengrove is also passionate about gardens. Combining her talents with the two architects, the trio set about creating a very structured, formal garden–very architectural, if you will–comprising a series of ‘garden rooms’ around two perpendicular axes.

Over the years, the garden has expanded, taking in a woodland walkway across a swing bridge and accomodating over two dozen contemporary sculptures. Meanwhile the property has opened two galleries, devoted to New Zealand art and architecture.

I hope that Ōhinetahi will continue to be one of the best, most visited and enjoyed gardens, park, house and art gallery in New Zealand.Sir Miles Warren

John and Pauline moved away in the 1980s with Sir Miles buying out their share of the property, then retiring from Warren and Mahoney in 1994. Ōhinetahi became a place of peaceful rest until the first of the big Canterbury quakes in September 2010. The damage to the homestead was severe and Sir Miles was lucky to escape with his life. The top storey had largely collapsed and the decision was taken in the repair effort to remodel the house into a safer two-storey structure, more typical of villas of its time.

It was a wise move, as the even more severe earthquake of February 2011 was to prove. Although damage to the house and grounds did occur, it could have been so much worse.

Once restored to its glory, Sir Miles took the decision to gift Ōhinetahi to the City of Christchurch and the nation in 2012. It is now run by the Ōhinetahi Charitable Trust with a remit to maintain and improve the house and garden’s facilities, while sharing them with the public.
