The $1.025 billion deal is worth $925 million in cash, with the balance to be made up in advertising.
"We're still to sell our NZ TV rights and yet to monetise mobile platforms," said Grant.
"This is a fantastic outcome for the game and starts the journey the Commission was formed to oversee.
"The cash that comes from the agreement, used wisely, will provide a funding base to sustainably grow our game from its grassroots to the elite levels.
"Very significantly, and a factor that played heavily in the Commission's final decision, is the release of Nine, Fox, and most particularly News, over all their rights in regard to future agreements.
"We hope the game's stakeholders see this agreement as a confirmation of their decision to put in place an Independent Commission, and one that unlocks the promise that came from this formation.
"It's been a difficult, complex and, at times, stressful process.
"Everyone in the sport can feel a great sense of pride, where fans of the highest-rating code in the country can look forward to seeing great matches week in and week out."
