The hotel, which is more of a hostel, is located near Patong Beach, Phuket Simon Cabaret and Jungceylon Shopping Centre, which are popular tourist attractions.
Eyewitnesses said they later saw Hamish carry Chatchaya, who was unconscious, from the rooftop pool area down to reception and asked staff to call an ambulance.
Phuket Express reported hotel staff contacted the Kusoldham Foundation and Chatchaya was rushed to Patong Hospital.
It said the full names of the couple and also the hotel were withheld by police pending the investigation.
Chatchaya, from Thailand’s Phetchabun Province, was pronounced dead around 2pm, about half an hour after her arrival.
Hamish, meanwhile, had reportedly returned to his room to take a shower before telling hotel workers about half an hour after the incident occurred that he planned to visit his girlfriend in hospital.
The swimming pool and Hamish’s room were sealed by police after they were informed about Chatchaya’s death.
A sign outside the pool reads “Swimming pool closed”.
Photos from within the hotel show the New Zealand man’s room has also been cordoned off. A note on the door says “Out of order”.
“We are aware of the media reports,” an Mfat spokeswoman said.
The Herald understands also that the New Zealand man was in Phuket for a holiday and is not residing in Thailand.
