Given a choice between wine tasting in Blenheim or Martinborough (New Zealand) which area would you choose? I'm planning a holiday in New Zealand - will be biking the West Coast of the South Island, ending with the train trip over the alps to Christchurch. Have a week afterwards and trying to decide where to spend it. I definitely want to do some wine tasting, and know a winery I like in Martinborough. That being said, I was also thinking of containing myself to the South Island on this trip. Is the Martinborough region better, worse, the same as Marlborough/Blenheim?
