The 26-year-old Papua New Guinea international hooker will join up with his new teammates in early January as preparations for the 2018 season intensify after the successful conclusion of negotiations with head of rugby Keiron Cunningham.
Leigh Centurions head coach Neil Jukes said: “Kurt’s signature is a huge coup for the Club.
“On and off the field he will add great leadership values and bring the quality trends he has developed from two elite environments in the Broncos and the Raiders.
“His energy, control and running game will be infectious for the players around him and with the staff look forward to enhancing those skills further.
“He’ll join up with the boys after the New Year and jump straight into our preparations for 2018.”
