To be honest, if you don't have need to travel to a particular area of Auckland then you will not know.
Even though I have now lived in Auckland (near CBD) for 15 years, I would be pushed to explain over the phone to someone how to get there.
As Sophia said thats what google maps are for or there is an alternative, a good old map book.
Now back to topic - I would aim for HFF, Mt Roskill and Pupuki (over the bridge). I have not visited either Aqua World or Aqua Village. There are the Animates shops but they do vary in quality, depending on who is working there - if its a knowledgable fish keeper then they can be pretty good.
