At that time of the morning with the reduced hours at the parks, the buses won't be running until 8am, since they usually start running abut an hour before park opening. That won't give you enough time to go to a park and make the transfer to the Poly bus. If you have a car, drive, it's about a 20 minute drive from AKL to the Poly. If you don't, I'd take a cab.
