KiwiRail is looking at joining Air New Zealand to introduce vaccine mandates to travel between the North and South Islands.
Air New Zealand chief executive Greg Foran last week said the airline will require all domestic passengers to be fully Covid-19 vaccinated or produce a negative test result from the middle of next month.
And KiwiRail says senior staff are considering various options for vaccine mandates for travellers on the Interislander ferries between Wellington and Picton.
A KiwiRail spokesman said there is no firm timeline for a decision. In the meantime, the ferry operator is enforcing the Government requirement to wear masks while travelling.
