wineries

has great climate for wine growing? Don't understand why there aren't masses of wineries in the Bay of Plenty in New Zealand when it's one of the sunniest spots in NZ and places like Gisborne, Hawkes Bay, Marlborough are stuffed with wineries? Any one have any ideas? Thanks

I know that Walt Disney's daughter has one but I was wondering if the company itself owns one for like souvenir purposes at the park.
