Holders of the Sir Fred Allen Challenge Cup, the Ranfurly Shield equivalent of Auckland club rugby, are Papatoetoe, where Luke Mealamu, brother of Keven, has stepped up as head coach to replace Geoff Moon.
The south Aucklanders kick off with a cup defence, against Waitakere City.
Other contenders will be Suburbs, making solid progress under the astute coaching of Ramsey Tomokino; Marist, under new coach Paul Biddle, 2012 grand finalists looking to go one better, and with experienced locks such as Gene Waller and Filipo Levi looking to free up space for talented outsides such as Leroy Van Dam and Sam Vaka; Ponsonby, who will be stung after being toppled from their perch last season; and Pakuranga, again under the aegis of Auckland assistant coach Paul Feeney.
The east Aucklanders will hope to see game time out of fringe Blues such as Malakai Fekitoa and Joe Edwards.
University have a very young squad, and have recruited some prime schoolboy talent out of King's College and Sacred Heart College.
Waitemata welcome back an old favourite in Amasio Valence, who has played for Suburbs in the last two seasons.
College Rifles have recruited Orene Ai'i and Brad Mika to bolster their mostly home-grown squad.
Today's marquee match pits Suburbs against the champs Grammar-Carlton at Shadbolt Park. All matches will kick off at 2.45pm
