The Minister of Foreign Affairs says there has still been no significant explanation for a string of tourist deaths at a Thai hotel, including that of New Zealander Sarah Carter.
The Governor of Chiang Mai says the deaths of Ms Carter, a British couple and a Thai tour guide - who all stayed at the Downtown Inn last month - are a coincidence.
Mr McCully told Morning Report there is no evidence to suggest the deaths are not a coincidence, and New Zealand officials in Thailand are still seeking forensic information.
Looking at the transcript of the governor's statement, Mr McCully says, "Clearly they're concerned to try get back to a normal situation from a tourism point of view.
"We would obviously take the view that that wasn't appropriate if there were lingering questions."
Mr McCully says the ministry will consider issuing a travel advisory that puts on record any concerns New Zealanders should be aware of before travelling to Thailand.
