A New Zealand property and building consultancy with offices in Auckland, Wellington and Christchurch, running two lines that meet in fire defect litigation: a passive fire services practice covering fire-resistant materials, systems and construction techniques that limit the spread of fire and smoke through a building, and a building disputes practice whose expert witnesses give independent evidence on exposure, reinstatement and repair. In a market shaped by the weathertightness claims, passive fire is the defect class now following the same path.
