The youngster won the FIA Junior WRC in 2021 and returned to defend his crown this year alongside additional WRC2 outings with a Fabia Rally2.
Although Pajari was unsuccessful in his junior title defence (he finished third in the one-make series), impressive performances in the WRC’s premier support category - including a stage win on home soil in Finland - have whet his appetite for a full assault in 2023.
Co-driven by Enni Mälkönen, Pajari will drive a Škoda prepared by leading WRC2 team Toksport.
“What lies ahead next season sounds like a dream come true,” he said. “I’m of course thrilled and looking forward to making the most out of such an opportunity.
“There could not be a better partner for us for the future than such a wonderful and thoroughly professional team like Toksport, but there is still much work to be done this season before I can switch focus to next year,” he added.
