Ngai Tahu Property's Pita Te Hori Centre – comprising the Iwikau and Te Urutī buildings - is a shining example of honouring and celebrating our heritage while embracing innovation and a sustainable future.

Situated on the historic site of the King Edward Barracks, the buildings have been designed to optimise energy and water efficiency while creating a healthy work environment, including onsite solar energy generation, and plentiful cycle facilities shared between both Iwikau and Te Urutī

A key feature of the development is the central aquifer heat pump which provides heating and cooling to both buildings and is also a part of the Christchurch District Energy Scheme – the first of its kind in New Zealand.

Between the buildings, Ngā Māra a Te Wera (The Gardens of Te Wera), is a place of respite that reflects the site’s Māori, European, military and police histories.
