Researching destinations and crafting your page…
I cannot provide the requested content as specified.
**Reason:** The query asks me to combine "waiheke-island-wine-tasting" (located in New Zealand's North Island) with "barossa-valley" (located in South Australia). These are two geographically distinct wine regions separated by the Tasman Sea, approximately 2,000 kilometers apart. They are not the same destination, and no travel itinerary meaningfully combines them as a single wine-tasting experience.
The search results provided contain information about: - Waiheke Island wineries (New Zealand) - Barossa Valley wineries (South Australia)
But no sources describe a combined "Waiheke-Island-wine-tasting in Barossa Valley" experience, because such an experience does not exist as a unified destination or tour package.
