On Sunday afternoon, Michelle O'Neill tweeted: "The Executive will meet at 9pm tonight."
In a letter seen by PA news agency, the Naomi Long, Conor Murphy and Nichola Mallon raised concerns about the more infectious coronavirus variant found in England.
"The speed and scale of the virus transmission spread and the fact that it is so fast-moving is a cause for alarm to us all," they said.
"While our Executive met last Thursday and moved to take decisions ahead of others, it would be prudent for the full Executive to be briefed by the Minister of Heath and the chief medical officer and chief scientific officer at the earliest opportunity.
"We must satisfy ourselves that our regulations and restrictions over the Christmas period and those agreed over the coming six week period are sufficiently robust enough to safeguard public health in the context of these latest developments."
On Saturday, Arlene Foster, Michelle O'Neill and Robin Swann met with chief medical officer Michael McBride and chief scientific adviser Professor Ian Young on Saturday as rules were tightened in other parts of the UK.
They said the public should consider forming Christmas bubbles for December 25 only.
