They were about 300-350m off the shore, Mr Fraser said.
The water was about seven or eight metres deep, with about three or four metres of weed at the bottom of it, Mr Fraser said.
Family and others on the shore did everything they could to help, he said.
"A gentleman there who immediately started swimming out, another lady managed to grab another kayak and drag it down to the beach and headed out.
"But despite their best efforts it was just too late.''
Family members and relatives who were waiting at the holiday home that overlooked the scene were too distraught to speak when approached by the Herald yesterday.
"We are very, very sad and very tired,'' said a female relative at the house.
The upturned kayak, a paddle and the the lifejacket were recovered first.
The man's body was recovered by divers about 4pm and hauled onto a coastguard vessel. Divers found the girl's body a little over an hour later.
Their bodies were taken to Rotorua Hospital for a post-mortem examination last night.
Their deaths have been referred to the Coroner.
