The Lyttelton Port Company is advancing a significant expansion project aimed at increasing the South Island’s shipping and freight capacity amid growing demand and ageing infrastructure. The Christchurch City Holdings-owned port is developing a new deepwater wharf and container terminal on reclaimed land at Te Awaparahi Bay, with completion targeted for 2031.

The initiative follows extensive recovery efforts after the 2010-2011 Canterbury earthquakes, which caused substantial damage to nearly half of the port’s nine wharves. While core services and the oil berth resumed quickly, Cashin Quay 2 required complete rebuilding. The repair and strengthening work over the past decade resulted in multimillion-dollar asset writedowns and a $450 million insurance settlement.

The $821 million Te Awaparahi Bay Expansion and Resilience project will relocate major port operations eastward. Dredging of the berth pocket is scheduled to begin later this year, with construction set to commence next year. The new facility will feature a 388-metre deepwater wharf, a five-hectare container terminal, and four ship-to-shore cranes supported by semi-automated yard cranes.

Designed to accommodate larger vessels capable of carrying up to 15,000 twenty-foot equivalent units (TEUs), the terminal will double Lyttelton’s annual berth capacity to 850,000 TEUs. By comparison, the nation’s largest port in Tauranga currently handles about 1.2 million TEUs annually.

Lyttelton Port Company chief executive Graeme Sumner emphasized that the expansion reflects confidence in Christchurch’s economic growth and the South Island’s role in national trade. He noted that the combination of ageing facilities, rising export volumes, larger ship sizes, and increasing trade demands made the investment necessary. Sumner added that rebuilding some container berths would take at least three years and disrupt operations, while the expansion enables uninterrupted port functioning.

Environmental considerations form a key part of the project. The port has implemented an extensive construction environmental plan and sustainability framework aligned with international best practices. Under the Kaimoana Management Plan, more than 7,000 marine organisms have been relocated, and a disclosure report tracks port-related land and habitat changes since 1875. The company seeks to become net biodiversity positive relative to the 1875 baseline.

Marine piling activities during construction will be regulated by a management plan that includes an observation zone. Piling will halt if dolphins are detected within the area until they have safely departed.

Lyttelton Port Company reported strong financial results for the year ending June, with revenue rising 9% to $226 million, operating earnings up 22% to $77 million, and net profit growing 40% to $35 million. Container volumes remained steady at 427,462 TEUs, while total bulk cargo increased 9% to 3.83 million tonnes. Gains were noted in dry bulk (up 19%), coal (14%), bulk fuel (3%), and vehicle volumes (11%). Log exports declined 17%, affected by high shipping costs and alternative market demand. Grain, fertiliser, and stockfeed volumes strengthened alongside favourable agricultural conditions.

Christchurch City Holdings is providing $300 million toward the Te Awaparahi Bay expansion, with the remainder funded through port company debt. The development is expected to position Lyttelton Port as a key trade gateway connecting South Island businesses with international markets for decades to come.
