This morning, a judge sentenced Stafford to 2 to 12 months in Erie County Prison and at least three years probation.
Her conviction and sentencing arose out of an incident that happened in Johannesburg in February 2016, when Momberg made an emergency call to say she'd been robbed.
Handing down her ruling, magistrate Pravina Raghoonandan said some may think the sentence was harsh but it was meant to signal that racism will not be tolerated in South Africa.
"Looking at our courts and the number of increases in respect to these offences, it is time a loud message is sent to every race, every person in the country, that this can't go on any longer", Baba said.
"This case has become public interest, some may think the sentence is harsh ..."
He further told the court that Maru released sensitive official documents of NAHCON to one Ibrahim Wala, a self-acclaimed Human Rights activist without authority to do so.
"This is a landmark ruling".
Momberg's jail term is being hailed as a precedent and a clear indication that the use of the k-word and other racial slurs is not meaningless in South Africa.
Hamisu said that the convict was an accountant attached to the office of the Accountant-General of the Federation (OAGF) but seconded to the National Hajj Commission of Nigeria (NAHCON).
Momberg's defence intends to apply for leave to appeal next week. She is appealing this order.
Defendant Estella Toteh, 49, found guilty of theft of property, has been sentenced to eight years at the Monrovia Central Prison by the Brewerville Magisterial Court, outside of Monrovia.
