Beniwal, who was scheduled to visit Hmuifang Tourist Resort, about 50 km from here, cancelled her programme, sources said.
As she was leaving with a short notice, it would be impossible to organise the ceremonial farewell dinner for her, state Protocol department officials said.
"An official farewell function where she would be accorded a guard of honour would be organised at the Lengpui Airport the day she is leaving which would be attended by the acting Chief Minister R Lalzirliana (Home Minister) and senior officials," the officials said.
Beniwal was transferred from Gujarat to Mizoram and sworn-in as the state Governor on July nine and she had arrived here on the same day.
However, the Governor, who had a running battle with Narendra Modi when he was Gujarat Chief Minister, was sacked last night, just two months before her tenure comes to an end.
