According to the Herald, the Warriors are unwilling to fork out the seven-figure sum for Johnson and have told him to explore his options.
Johnson last year re-signed with the Warriors on a two-year deal worth over $1 million a season.
However, the Warriors are keen to look elsewhere for a better long term option for the No. 7 role, due to Johnson’s lack of consistency.
Warriors CEO Cameron George confirmed the club was in no rush to re-sign the playmaker.
“The club are open-minded about the future and we’ll talk to Shaun and his management when he gets back from overseas about the future,” George told nzherald.co.nz.
“We’re very open-minded and with any recruitment decisions it’s about the team and the club first. But whilst we’re being open-minded about the future, we’re not going to be scared to make big calls on any player.
“We want to win the competition and we’ll be doing everything recruitment-wise to get the best people in the club to do so.
“We are not scared about making any big calls on our roster because we want to win this competition and everyone’s always under review.”
