The home side's greatest challenge is likely to come from neighbours Midlands who will welcome returning Olympians Cat Finlayson, Sam Charlton and drag flick exponent Clarissa Eshuis alongside Black Sticks goalkeeper Sally Rutherford.
North Harbour will also give the Aucklander's a run for their money with in-form Olympic goalkeeper Bianca Russell joining fellow Black Sticks Petrea Webster and Rhiannon Dennison in the Harbour side.
Meanwhile, the men's competition looks a lot less clear cut with Auckland, who shared the title with Central last year after the final was called off due to snow, again the top contender.
Keen to claim the title outright this year, Auckland have bolstered their squad with the inclusion of Australian star Brent Livermore, who will join Black Sticks Marcus Child and Arun Panchia.
Midlands, with Olympians Blair Hopping and Scott Deavin (Australia), will keep the Aucklander's honest as will a young North Harbour side featuring many of the team that won this year's under-21 national title.
