At the time, it was alleged that Dlamini was on African National Congress (ANC) party business as the head of the Women’s League.
Dlamini caused outrage in January when a meeting of Parliament’s social development portfolio committee was cancelled ostensibly for her to attend the ANC lekgotla.
But it later emerged that she had travelled to Addis Ababa where the ANC Women's League was launching a young women's desk.
In a written response to Parliament, the department says Dlamini was attending the 9th African Union Gender Pre-Summit, accompanied by a parliamentary officer and her chief director of communications.
