you would be better going out through immigration and checking your hand carry bags in the Left Luggage. To get to the Pier or the Wing you will have to go through Security then go upstairs 2 levels. Then the same thing to get back to arrivals level Since your flight is 12 hours later it probably will not have a gate allocation and you would rue having to walk all the way to the Pier to get your bags if your departure was at Gate 1.
