League officials said their primary concern was for the health, wellbeing and safety of all players, staff and their families, especially over the Christmas period.
Organisers said that as a result of the number of cases in the Mariners' camp, the game postponement was a necessary step to ensure the spread of the virus was limited and the health of their clubs was ensured.
A statement said a new date would be decided for the postponed match "as soon as possible".
It could lead to a fixture logjam for the Wellington team, who already have league games scheduled against Adelaide (January 1), Brisbane (January 5), Newcastle (January 8) and Perth Glory (January 16) in the coming weeks.
The A-League women's match between the Wellington Phoenix and Newcastle Jets will go ahead as scheduled at 8:45pm (NZT) in Gosford.
However, it will take place behind closed doors without crowds in attendance.
