Environment Southland has sold 3.75 million shares in South Port New Zealand for about $30 million, trimming its stake in the Bluff port company from 66 per cent to about 52 per cent while keeping a controlling interest.
The sale, announced to the NZX on 1 October, was priced at $8.00 a share and handled by Jarden as bookbuilder and underwriter, with settlement set for 5 October. The parcel represents about 14.3 per cent of South Port's issued shares.
The regional council said the proceeds would go into a broader investment portfolio. Income from that portfolio is applied first to maintaining key reserves, including a disaster recovery fund, and then to reducing general rates. Gains that are not drawn down stay invested in managed funds.
Council chairman Jeremy McPhail said the move was about spreading risk rather than any loss of faith in the port.
"Essentially, reducing our shareholding is about reducing risk by not having too many eggs in one basket," he said. The council's financial and economic analysis showed ratepayers would get better returns from diversifying, particularly while the port was performing strongly.
"South Port is a successful business and a strategically important regional asset," Mr McPhail said, adding that the council was proud to remain its majority owner.
Long signalled
The partial sell-down has been on the table for some time. The council consulted on reducing its holding to as low as 51 per cent in its 2024–34 long-term plan, and appointed a financial adviser last year to test the options. In September Mr McPhail said any decision would depend on whether a proposal could deliver an appropriate financial outcome for ratepayers, and in the days before the announcement the council held extraordinary investment committee and full council meetings on South Port matters with the public excluded.
The sale follows a record year for the company. South Port posted an after-tax profit of $16.1 million for the 2026 financial year, with cargo volumes approaching 4 million tonnes on the back of agricultural exports, aluminium from the Tiwai Point smelter and project cargo for wind farm construction.
South Port's annual meeting is scheduled for 28 October, when Nicola Greer is due to take over from Philip Cory-Wright as chair.
What changes for ratepayers
For ratepayers, the practical effect is a shift from relying on a single dividend stream to drawing on a managed portfolio that the council says is designed to protect its reserves first and ease rates second. The council keeps control of the company through its majority holding.
For South Port, the sale broadens a share register that had been dominated by a single holder, bringing new investors on board at a time when the Bluff port is handling record volumes.
