NSW Waratahs fullback Israel Folau is understood to be on the New Zealand Warriors' radar.

Could Wallabies fullback Israel Folau be a New Zealand Warrior in 2018?

The Auckland-based National Rugby League club are understood to be interested in the former Australian Kangaroo, who starred for the Melbourne Storm and Brisbane Broncos between 2007-10.

Folau, 27, has played rugby union for the New South Wales Waratahs since 2013, switching over following a short stint in Australian Rules.

Rugby League Week are reporting the Warriors have shown interest in the talented code-hopper, who could bolster their perennial problem in the centres.

﻿It wouldn't be a surprise if the Warriors have identified Folau as a transfer target.

His fiancee Auckland-based Silver Ferns' shooter Maria Tutaia will again play for the Northern Mystics in the new ANZ Premiership.

Folau launched the 30-day countdown to the inaugural Brisbane Global Tens tournament last week that will be held at Suncorp Stadium over February 11-12.

Last week he poured cold water over a future return to the Broncos telling The Courier Mail he was happy in the 15-man code.

"It's always good to come back here," Folau said.

"Playing at Suncorp is going to be great. I can't wait. I've still got family here and I miss them.

"I've shared some great memories here. It's a special place for me. I'll always be a Queenslander."

Penalty goals will be scrapped in favour of long range tries and Folau said it was the ideal platform to kick off the new season.

The Australian and New Zealand Super Rugby franchises will enter teams in the Tens along with French outfit Toulon, South Africa's Blue Bulls, the Panasonic Wild Knights from Japan and a Samoan team.
