Boso moved from Honiara-based club Marist FC after helping them reached the semi-finals of the OFC Champions League this season which caught the eyes of Team Wellington manager Jose Figueira.
The central defender had a brief stint with Miramar Rangers FC in the New Zealand winter league before teaming up with the Oceania champions.
However, an injury saw him sidelined just before the ISPS Handa Premiership got underway putting a halt to his debut on the New Zealand scene.
With determination and desire to make the final travelling squad for the FIFA Club World Cup, Boso put in the hard yards behind the scenes to convince the coaching staff.
“I worked hard every day and the coach never gave up on me,” Boso said.
As a player, Boso said it’s a dream come true to have the chance of playing at the highest level in club football.
“For me it is a golden opportunity to be part of this squad.
“I always dreamed of this opportunity now it’s not a dream it’s here and I am happy to be part of Jose and Scott’s philosophy.
“It’s a privilege to be training and playing with the top players in our region and most of them are professional players.
“It’s a big step for me to be part of Team Wellington but every day I work and work to achieve more for this club in the future,” the Solomon Islands international added.
Team Wellington will take on Al Ain on Thursday 13 December in the FIFA Club World Cup play-off.
