Retallick's influence as the world's best lock and 2014 player of the year is,
clearly, breaking barriers around what forwards can expect to earn here and abroad.
This is why NZ Rugby is very open about the fact they will work with the likes of Retallick and Beauden Barrett to allow top end players to take sabbatical options, in what are still expected to be long-term commitments through to the World Cup in 2023.
Japan appears a much more likely destination for Retallick to take a potential year-long spell out of New Zealand, and the Herald understands Kobe are leading negotiations for the 27-year-old's services.
Japan's double season lure in 2020 has been well documented. All Blacks captain Kieran Read is among those expected to feature there next year.
With Wayne Smith on board as general manager, and former Chiefs player development manager Dave Dillon the head coach, connections for Retallick at Kobe are clear.
This year the Dillon-Smith combination guided Kobe to their second Top League title with a 55-5 victory over Suntory in the final.
With a squad that included Dan Carter, Richard Buckman, Andy Ellis, Tom Franklin, Hayden Parker, Adam Ashley-Cooper and Codey Rei it is not hard to see why.
The club is, no doubt, keen to continue such success. Their pursuit of Retallick certainly signals those ambitions.
