Gracefield is an industrial suburb of Lower Hutt City, located at the bottom of the North Island of New Zealand. Up until the 1980s, Gracefield and neighbouring Petone were home to woollen mills, railway workshops, car assembly and meat processing plants. But when protective tariffs were lifted in the mid-1980s, many of these industries ceased. The headquarters and principal laboratories of Callaghan Innovation are in Gracefield, in premises developed largely from the Physics and Engineering Laboratory of DSIR.
