I thought I was setting myself up with the fish comment
I think you will find if you have a full day you could fit a couple of gimblet gravels wineries in before lunch, then across to havelock for a late lunch at craggy, then te mata after lunch and depending on your enthusiam even clearview after that though you may be pushing it if you stop for lunch at Craggy. If you have some money burning a hole in your pocket you must splash out at Craggy Range's Terrior restaurant which is the best in the country in my opinion (and ive been to all the top ones except herzog). Te Whau would be my next pick on Waiheke. Lunch on the deck beneath Te Mata Peak is hard to beat, the food, service and wine list is impecible.
Last time I was in the bay drove from Taupo in the morning. We did Unison, Trinity Hill, Craggy Range and Te Mata before 3pm and retired to the motel for cricket on tv and an antipasto we threw together from Hastings New World supermarket which is an excellent shop for wine friendly provisions (hastings is between gimblet gravels and havelock north). Buy yourself a bottle of Te Mata Coleraine, Craggy Range Le Sol or the like, commit infanticide and enjoy. Only will cost you $3.50 Australian at current rates?
Failing 5 in a day perhaps clearview next day and esk valley/mission on the way out. depends how wild you wanna go with the winery hopping but it is possible. if it is a clear sunny day you might want to enjoy Te Awanga, the beach and the awesome outdoor restaurant Clearview offers.
Hamilton area hasnt got any wineries worth dragging you away from the fishing though viligrad winery near hamilton does a great hearty country style spit roast lunch on a sunday. awesome food but unfortunately the wine is crap. Those dalmation types know how to cook a good feed
Taupo (aka event capital of NZ) has a great wine shop, one of the best in the country called scenic cellars right down on the lake shore on the main road through (a couple of shops away from the kfc, can't miss it). The deli shop in the front of it does allpress coffee too if you want to try one of the best coffee brands here too
