"I woke up in the middle of the night last night with serious cramps and nothing to take for them," he said yesterday.
The couple hoped someone might come forward with information about the theft and the publicity would warn others to "make sure you have got the really valuable stuff locked away or on you".
The theft had "come as quite a shock", Mrs Burrows said.
"I feel violated," she said.
"Even the fishing licence I had just bought and my bait, some dehydrated squid, were gone," Mr Borrows said.
The theft had caused the couple stress, but they were not going to let it ruin their holiday - their second visit to New Zealand.
Since the theft, they have had offers of help from the owners of the Leith Valley Touring Park, where they are staying and others, "but that's typical of New Zealand", Mrs Burrows said.
"I'm sure there's the odd nasty person, but I didn't meet him. He just stole stuff from our van."
