Auckland's Eden Park is being lined up to host a lucrative rugby league double-header in 2013 with the NRL looking at adding an extra round that season. The NRL are looking to stage the round at three venues. Eden Park could potentially host two matches including the Warriors on a Friday night, Brisbane would enjoy a triple-header on Saturday and three matches would be played at ANZ Stadium in Sydney on the Sunday. The NRL believes the concept is commercially attractive; suggesting $A3m ($NZ3.75m) in gate-takings could be split evenly amongst the clubs. "The blockbuster round concept is something which we would like to discuss with the clubs but we believe it could be an exciting new concept for fans," said NRL football operations director Nathan McGuirk. Club chairman and chief executives will vote on the concept today in Sydney. There are also continued suggestions of Auckland getting to host a State of Origin game. There are also hopes to play the Origin games on Mondays from 2013 with an eye on player welfare. Eden Park has hosted a rugby league World Cup final, an Anzac test and this year the Warriors kicked off their season there against the Eels.
