"While the Pasifika Super Rugby teams are a highlight, so is seeing the Pacific sevens teams winning big matches, and watching the likes of Manu Samoa, Ikale Tahi and the Flying Fijians take on top level teams and sticking it to them - such as when Fiji beat France 21-14, in Paris in 2018," he said.
"Knowing what happens behind the scenes and the lack of the resources these nations contend with, and then seeing them perform well is really satisfying - as is supporting the players and making sure everything is in place so they can play."
Of Ngāti Kahungunu descent, Clarke said the role had taught him a lot about "diplomacy, and the power of maintaining good working relationships".
He also paid tribute to the role of Pacific Rugby Players Chair Hale T-Pole and fellow founding members Seilala Mapusua and Deacon Manu in helping to establish the former Pacific Islands Players Association in 2013.
"I have such huge gratitude towards these guys…you know, sometimes people asked why a Māori boy was leading a Pacific island organisation - not often but it did come up occasionally.
"I always saw it as a positive - I could approach the unions from a neutral perspective, which worked for me…but whenever I needed advice or guidance, particularly around Pacific cultural values, Hale, Seilala and Deacon were there to offer it. I am very grateful."
Clarke was also proud of Pacific Rugby Players' role in helping to strengthen rugby governance in the region and working with organisations such as New Zealand's Ministry of Foreign Affairs and Trade to enhance the women's programme in Fiji.
