In the Tri Nations matchup of defending champion New Zealand and Australia, the All Blacks will be bolstered by the return of captain Richie McCaw. Kiwi coach Graham Henry is under extreme pressure after the legendary All Blacks dropped consecutive matches for the first time since 2004.

Australia is pursuing its first win on New Zealand soil since 2001 and will be aided by heralded new coach Robbie Deans, a former All Black who has the Wallabies unbeaten in 2008. Wallaby standout Stirling Mortlock is back to captain the visiting side and earn his 68th cap.

Also in the land of the Long White Cloud, the Air New Zealand Cup features 14 elite teams in a round-robin format. This Sunday, MediaZone Rugby concludes opening round coverage of the ANZC at 10:35pm ET with Counties Manukau v. Auckland live from Eden Park, capping the much-awaited seven-game slate.

After losing 15 players -- including nine All Blacks -- Auckland's lineup is distinctly different than the one that lifted the Cup but the champs are tabbed by many to repeat. Counties Manukau is looking to right itself after a dismal campaign and will be boosted by New Zealand Sevens captain DJ Forbes.

The history of South Africa's Currie Cup dates back to 1899, making it one of the oldest rugby competitions in the world. Leading the trifecta of domestic offerings, MediaZone Rugby is presenting the Golden Lions v. Western Province, two teams locked in a tight standings battle, live from Johannesburg, South Africa.

The third-place Golden Lions missed out on a chance to occupy first place with a narrow loss last week but are contenders behind coach Eugene Eloff's leadership. Western Province last lifted the trophy in 2001 and with the momentum from a 40-point victory a week ago, coach Allister Coetzee's squad has title aspirations once again.
