"It was unbelievable. We were made to wait for the news but when it did come everyone was over the moon," he said.
"It really was the icing on the cake to what was a brilliant club celebration, and the team really deserved it because they stepped up their performance.
"We really pushed for that bonus try and everyone supported each other in all areas of the pitch.
"It's going to be a real challenge playing some of the teams in the next round. We'll take one game at a time because we still have a long way to go."
Marist St Michael's will now battle it out against the three local teams and Poroporo who finished second in Division 1 whilst Arataki, Opotiki and Paroa complete the final eight after all dropping down.
The new competition will start this weekend with all teams starting afresh and it will be a difficult challenge for Marist St Michael's to contend for one of the four promotion spots into Premier One for next season.
But coach Mike Lewis is relishing the prospect and has targeted the Whakarewarewa clash as the most difficult game on the fixture list.
"It's great to have so many Rotorua clubs fighting it out, and it will make the games fantastic to watch," he said. "A lot of work has to be put in to step up but I have faith in the players and as long as we stick to game plans and work hard we can get results.
"The Whaka game will certainly be one to watch. They were very unlucky to drop down and they now have a big point to prove. We have to compete in every single game and hopefully we can take the club's positivity into the competition."
Over the weekend the club hosted celebratory activities including a formal dinner where former player and current New Zealand Sevens coach Sir Gordon Tietjens gave a speech.
And Defarias believes Marist St Michael's will go from strength to strength especially because of its emphasis on youth.
"So many positive comments and feedback came from this wonderful weekend, it was certainly one we won't forget in a hurry," he said.
"The club is always looking to expand, and we put a lot of hard work into the youth section which is where the future is. We will most definitely be here in another 80 years to come going stronger than ever I'm sure."
