Graeme Sumner: Lyttelton Port CEO on the port's planned $821m expansion

Lyttelton Port says growing trade and ageing infrastructure have made its $821-million-dollar expansion necessary. The project includes a new wharf and container terminal, lifting capacity to around 850 thousand containers a year. Chief executive Graeme Sumner says the port's running out of capacity - with 92 percent of ships built today unable to fit in the current port.
