In 2012, he was selected to represent the Golden Lions at the premier rugby union competition for high schools in South Africa, the Under-18 Craven Week.
He featured in all seven of their matches in a disappointing season that saw the team finish second-bottom of the log[10] which meant they had to compete in a relegation play-off to retain their Varsity Cup status.
Sekete started the play-off match in which UJ easily beat Varsity Shield runners-up UKZN Impi to remain in the top tier.
He scored two tries during the competition – both in a 113–3 victory over Border U21[17] – as the Golden Lions finished in third spot on the log[18] before losing to the Blue Bulls in the semi-finals, the only match of the season that Sekekete did not feature in.
[26] He was named on the bench for their opening match of the season against the Pumas and made his Currie Cup debut by coming on for the final twelve minutes of a 68–26 victory.
