Zied Ait Ouagram, an adopted Moroccan who fought for Tunisia at London 2012, secured a place in his second Olympic Games on the opening day of the Africa-Oceania Wrestling qualifying tournament in Algiers.
Ouagram, 17th in London before switching nationality last year to wrestle for the country of his parents, demolished African champion Mahmoud Sebie of Egypt 8-0 before a 10-0 victory over Tunisia's Wael Selmi in the under 75 kilogram Greco-Roman division.
He then then sealed his place with a narrower 5-4 win over Algeria's Akrem Boudjemline to secure an Olympic spot in Rio de Janeiro in the four-man round robin event.
“It is always an honour to take part in the Olympic Games,” he said.
“But, now we also want to do better, finish with better rankings and win medals of all colours.”
At least two Oceanian fighters will compete at Rio 2016 after Australian duo Vinod Kumar and Ivan Popov each secured berths.
Kumar came from behind to defeat regional rival Craig Miller of New Zealand 12-6 in the men's under 66kg competition.
Popov prevailed in the heavyweight under 130kg division with a win by fall over African bronze medalist Ali Bouachioum of Algeria.
Both lost their respective finals to Egyptian fellow qualifiers, however, with Kumar losing to Adham Ahmed Saleh Ibrahim Kahk 10-0.
Popov also lost 10-0 to Abdellatif Mohamed Ahmed Mohamed.
Egypt also claimed the gold medal in the under 85kg division, where Ahmed Mohamed Ibrahim Othman Saad edged Algeria's Adem Boudjemline 4-3.
Action is set to continue over the weekend with male and female freestyle competitions.
