NZ Warriors co-owner Mark Robinson predicts his team can win an NRL Grand Final in the next three years.

Robinson is the chief executive of Autex Industries, which owns 33 percent of the club, with the Carlaw Heritage Trust holding a 67 percent share.

In May, they purchased the club off former owner Eric Watson, who held the club for 17 years.

Autex has had a strong history with rugby league in New Zealand, dating back to 1979, when they first sponsored the Kiwis.

They took over the Warriors four months ago and after making the finals for the first time in seven years, Robinson believes they now have everything they need to succeed in the next three years.

Their ultimate goal is to win the club's first title in that period.

"What we're building for is the next three years - 2019, 2020, 2021," he told Newshub.

"We're looking at signing players, within and out of the club, that are going to be there for those three years and in that time frame.

"We expect to be the finals each of those years and we're expecting to get one, maybe two [titles]."

The bulk of the current Warriors squad will be around next season, with Simon Mannering the biggest loss, due to retirement.

Issac Luke is the biggest name off contract and Robinson insists they are in talks with the veteran hooker.

The only new player signed for 2019 and beyond is St George Illawarra prop Lesson Ah Mau.

"There are always going to be one or two who drop out, and there are always going to be a couple who come in,” said Robinson.
