Provided the entirety of what you want to do is wander up and down Queen Street and attractions very close to it and don't mind paying $32 for the privilege, this might be OK. If you were planning on checking out things like museums, galleries, parks, etc, you will not have enough time.
I personally think transport connections from AKL into the city are fantastic.
The cheapest way to get into the city if the A380 airporter bus and then the train. This is (from memory) just under $5 if you have a HOP card but is significantly more without one. It only takes an hour to get to Britomart which isn't much longer than the Skybus which is around 40 - 50 mins depending on traffic.
The Skybus is also $18 for the fare and $17 online purchases or $32 return It went up from $16 single far not long after Skybus took over the service from NZ Bus.
A day is plenty of time to go into the city and see the sights. I'd actually recommend catching the A380 airporter bus and train to Parnell and then walking around the Domain and then walk to the City.
