Kenya thrashed the Northern Africa side 67-0 in a match wacthed by opposition leader Raila Odinga among others.
Kenya Sevens forward Willy Ambaka was joined by Captain Davies Chenge, Andrew Chogo, Jacob Ojee, Elkeans Musonye, Darwin Mukidza, Martin Owilah, Peter Karia, Mohammed Omolo and Tony Onyango in the scoresheet.
Kenya picks five points from the win to move to 17 points and stay second in the Africa Gold Cup, three behind leaders Namibia.
Ambaka got things going for Kenya with Darwin Mukidza completing the conversion before he did so to Davies Chenge's try as the captain mauled over the Tunisian defence.
Lock Andrew Chogo would also go over to take Kenya's score to 21-0. Winger Jacob Ojee intercepted Tunisia's poor pass making a half-pitch run to score Kenya's fourth.
With little threat coming from the Tunisian side, they were punished after failing to keep their ball in their own 22 as flanker Elkeans Musonye went over.
Mukidza would also get on score sheet but missed his conversion before being withdrawn by Coach Ian Snook with Max Kang'eri coming in for him at inside centre.
Back to back tries from man of the match Martin Owilah amd Peter Karia took the score to 50-0 as Homeboyz duo of Tony Onyango and Mohamed Omollo extended the lead to 62-0. Ambaka would then close the scoring with his second and Kenya's 11th try.
Speaking after the win, Kenya Simbas head coach Ian Snook said:
"There were still a few disappointing things but we will see and fix that next week. Ambaka had a really good game. Managing to score twice as you saw it was a good afternoon. He is getting better and better and he is obviously talented."
"We would love to qualify directly to Japan and that's the goal, to beat Namibia. There is however a second chance of repechage but there is a big week ahead of us."
