A number of rule changes designed to further enliven the contest will make the role of TNT Express-sponsored referees more important than ever during the 2013 Super Rugby season.
The changes, implemented by Super Rugby governing body SANZAR, are designed to encourage even more running and attacking rugby.
They include changes to the scrum call, throw-in and ruck rules.
"It's fitting that, in a year of important rule changes, the referees will be highly noticeable in their bright orange TNT Express outfits," said Mark Hamilton, director of sales and marketing for TNT Express.
"TNT Express is proud to continue its association with Super Rugby as referee sponsor, which is now in its seventh year."
Referees will also receive further assistance from the TV match official during the 2013 season to determine a successful try.
The TV match official will now be able to review the events leading up to the try attempt, including forward passes.
