The Warriors' star halfback Shaun Johnson says it would be a mistake not to look at what's on offer from other clubs before making a decision on his playing future.

The 26-year-old is in the final year of his contract with the Auckland NRL club, and is reportedly attracting interest from multiple teams across the Tasman as well as the Super League in Europe.

Johnson says he has a lot of love for his current club, and although he would like to sort his playing destination for 2018 and beyond as soon as possible, he doesn't want to make a rushed decision.

"For me I have never been in this position before and I want to get it right," Johnson told Newshub.

"It's a business. I have been put in this position, so yeah, it would be silly of me not to and I think everyone would agree with that.

"I'm dedicated to this club and I'm looking forward to ripping into this season regardless of what happens in the future, so that's where my mind is at the moment."

Speaking at the launch of his upcoming documentary about his family ties to Laos, the birthplace of his mother, Johnson said the filming process really grounded him.
