All proceeds will go towards the upkeep of the First Church, Martinborough.
The next weekend, Mr Gulian will also speak at the Olive Harvest Festival, a showcase of Martinborough olive oil producers. Tickets cost $120 and include a three-course olive-themed lunch, activities, talks and tastings.
However, there is night market for all from 4-8pm on Saturday, June 28. And for a gold coin, anyone can go to the talks on Sunday.
The market will have more than 60 stalls, including hot food and drinks, creative crafts and gifts.
