Honestly, don't think about it further- stay here! Tuki Tuki House was an unbelievable place to stay in the Hawkes Bay with the most incredible views across the valley and to Te Mata peak. Plenty of wineries within a solid driving distance and the Hawkes Bay have plenty of bespoke wine tour companies that will drive you around all day for a very reasonable cost.
We had an incredible dinner at Craggy Range on the first night and then availed ourselves of the awesome kitchen and bbq facilities at the house for the rest of our stay.
The house, outdoors and hot tub are spotlessly clean and the transition from day to night is seamless and I really recommend putting the outdoor fire on and doing some stargazing while wrapped in a blanket (maybe with a glass of something nice). We saw several shooting stars and it was beautiful!
Close by there is Havelock North (cute and beautiful with interesting shops), a good beach with sand not stones and an amazing waterfall with a huge swimming hole if you can brave the cool water!!
Honestly, cannot recommend anything more!
