“All affected passengers are being moved to alternative sailings and are being contacted directly,” the ferry operator said.
Bluebridge services may also face delays or cancellations if swells reach the forecast height.
MetService meteorologist Silvia Martino said that in eastern parts of the country snow is expected to hit lower levels than it did over the weekend, making tomorrow the wintriest day of the week.
“Keep your eyes peeled for flakes falling right down into town on Tuesday morning if you’re in Otago or Canterbury, and for a fresh frosting up on the hills by Wednesday morning for folks as far north as Gisborne.”
Motorists in the south are advised to take care as snow, icy roads and reduced visibility could make driving hazardous.
“Check the snow level in your regional forecast to prepare if you’re going to be driving, particularly in Dunedin and Christchurch on Tuesday morning, and keep up with any updates on road conditions from NZTA Waka Kotahi and local council or emergency management,” Martino said.

Rain showers in the southernmost parts of the country will clear tomorrow thanks to developing high pressure, giving way to crisp sunny days.
However, the clearer skies will allow temperatures to fall even further overnight.
Widespread frosts are forecast through the middle of the week, with Wednesday morning marking the first of several bitterly cold starts.
Thursday could be the chilliest yet, Martino said.
“Even for our coldest month of the year, these are exceptionally cold overnight temperatures.
“Whitianga and Hamilton are forecast to be almost 10 degrees colder than average for this time of year on Thursday morning, at -3C and -5C respectively, and even the ‘winterless north’ is set to see frosty starts.”
Wet weather will then return to end the week as showers and cloud move in from the Tasman Sea.
