"The Herald's player ratings have been a big hit with our audience for a number of years, and with Kiwi rugby fans probably the most knowledgable in the world this often leads to some fierce debate," said NZME's Head of Sport Eduan Roos.

"With My All Blacks Ratings, we hope to further stimulate discussion around the country's favourite sport - and to bring fans even closer to the action."
