Enjoying the freedom and space at this beachfront camp site were several motorhomes and owners with champion dogs travelling from show to show around the North Island.
The dogs were able to run free, with their owners keeping a careful watch.
Upper Hutt woman Karen De Witt said they love coming to Wai-inu and have been camping for nearly five years.
"It's always very peaceful and we have our six dogs with us. It's perfect for us."
The De Witts were staying five days.
