Australia, New Zealand & the South Pacific - Day lockers available at Intercity Sky City bus terminal downtown Auckland?

Anyone happen to know if there is somewhere to store my carry-on luggage, which is all I'll be travelling with, at or near the Intercity bus terminal at Sky City in Auckland CBD? I may opt to check out of my hotel and go up the tower and do a little sightseeing in downtown Auckland and then hop the bus around noon for the ride to Rotorua and being able to ditch my carry-on for a few hours would sure make doing that much easier.

Thanks for any feedback. :)

There is a hotel connected to Sky City - you might be able to leave it with bellhop there. I don't think there was a checked bag area when I was visiting. I wonder if there isn't something down by the ferry terminal/bus station where you could check it in a locker ... anyone know?

There are lockers at the train station. The ones I used were downstairs by the tracks, but maybe there are also some on street level?
