I am studying abroad at Victoria University in Wellington for a semester, and decided to do a wine tour in Blenheim. I am so glad that my group of students chose this company. We were able to visit 6-7 wineries and the Moa brewery (everyone should check out Moa on their tour!)
At the end of the day, slightly intoxicated, I left my jacket at Nigel's place. He kindly shipped it back to Wellington for me. Nigel was friendly and helpful; definitely a day well-spent!
Be sure to allocate as much time as you can to this tour; you want to be sure to visit as many as possible. Nigel also met us at the bus-stop and dropped us off in town at the end of the day.
