Premier House (Māori: Te Whare Pirimia) is the official residence of the Prime Minister of New Zealand, located at 260 Tinakori Road, Thorndon, Wellington, New Zealand. A private house purchased for the prime minister's official residence when government shifted its base to Wellington in 1865, it was first greatly expanded and then, as its wooden structure deteriorated, shunned by the more modest political leaders on learning the cost of repairs.
