Nel-Peters was born on 28 June 1995 in Sedgefield, Western Cape, to Bennie Peters and Anne-Marie Steenkamp. Her half-sister, Franje, had cerebellar agenesis, and Nel-Peters said that she was the most significant motivator in her life; Franje later died on 4 May 2019, which Nel-Peters confirmed on her Instagram. While pursuing a bachelor's degree in business management and entrepreneurship from North-West University, Nel-Peters modeled part-time for Boss Models and Vision Management Cape Town. Nel-Peters graduated from university in March 2017, a few days before winning the Miss South Africa 2017 competition. She is fluent in both English and Afrikaans.
Pageantry
Miss South Africa 2017
Nel-Peters began her pageantry career representing Western Cape in the Miss South Africa 2017 competition on March 26, 2017, which she won. As Miss South Africa, she had the right to represent South Africa in both Miss World 2017 and Miss Universe 2017, but since the dates of the two pageants coincided, she was sent only to Miss Universe, held in Las Vegas, Nevada.
Miss Universe 2017
In the final round Steve Harvey asked Nel-Peters, "What quality in yourself are you most proud of and how will you apply that quality to your time as Miss Universe?" She said:
As Miss Universe you have to be confident in who you are as an individual. And Miss Universe is a woman that has overcome many fears and by that she is able to help other women to overcome their fears. She is a woman that nothing is ever too much to ask for and I think that is exactly who I am.
When asked about what she thought was the most important issue regarding women in the workplace, she said: She went on to win the competition and was crowned Miss Universe 2017 by outgoing titleholder Iris Mittenaere. Nel-Peters is the second titleholder from South Africa; Margaret Gardiner won Miss Universe 1978. Nel-Peters said during a segment at Miss Universe that she wants to use her self-defence workshops to help as many women as she can. This stems from an incident a month after she was crowned Miss South Africa, when she was carjacked at Hyde Park. She handed over her car keys but was forced into her car by the carjackers. She punched one of them in the throat and managed to run away and get help. In her capacity as Miss Universe, Nel-Peters visited the Philippines, Indonesia, Thailand, France, Mexico, Ecuador, India, Lebanon, Egypt, Malaysia, various cities in the United States, and her home country, South Africa. Nel-Peters ended her reign on December 17, 2018 in Bangkok, Thailand, the host nation of the 2018 Miss Universe pageant. She eventually crowned Catriona Gray of the Philippines as her successor.
