Whio Publishing

Marcus and Neil started Whio Publishing in 2016 to self-publish a book on New Zealand's caves. It is finally near completion and they are excited about the potential for future projects together as the Whio Publishing team.


Marcus Thomas is a graphic designer and writer/photographer based in Wellington. He has spent a lifetime exploring New Zealand’s underground wilderness and is at the forefront of exploration in New Zealand’s longest cave system, Bulmer Cavern. Among his many adventures, Marcus and his partner Linda are raising a family and encouraging them to venture into the outdoors.


Neil Silverwood is a professional photographer from the West Coast of New Zealand’s South Island. He specialises in photographing places many would consider too difficult or dangerous. Assignments have been as varied as exploring New Zealand’s wildest canyons to capturing skiing in war-torn Afghanistan. Neil regularly shoots for a range of magazines both within New Zealand and around the World but this project to photograph the diversity of New Zealand’s caves has been his most difficult to date.
