His body was recovered from Lake Wakatipu at the weekend, about 24 hours after he swam out to save his son.
The boy was rescued on Friday afternoon, but Mr Kisling did not make it back to shore.
Callan Grimmer, who helped lead the search, said the man's body was found on the lakebed about 50m from the Rees River mouth about 3pm on Saturday.
The police national dive squad had been called in.
Mr Grimmer said there had been a great effort from the wider public on Friday to help the family, and two helicopters and seven boats, including five from Dart River Adventures, were involved in the initial search.
"A member of the public managed to pull the boy in," Mr Grimmer said.
Emergency services were first called to Lake Wakatipu at Glenorchy about 2.55pm on Friday.
Senior Sergeant John Fookes said they were made aware at least one young person had drifted out into the lake.
The father had tried to help his son to get back, he said.
A St John spokeswoman said an ambulance, a first-response unit and a helicopter were sent to the scene on Friday.
One patient with minor injuries was taken to Lakes District Hospital in Queenstown by road.
A second helicopter was stood down before it arrived at the scene, the spokeswoman said.
A fisherman who was at Greenstone when the incident was reported also took part in the search.
The water near where emergency services were called to was waist deep, although there was a drop-off which could catch people out, the fisherman said.
Police thanked people who took part in search efforts and who provided assistance to family as the incident unfolded.
A rāhui is in place on an area that covers Glenorchy and the Dart River end of Lake Wakatipu until 3pm tomorrow.
The rāhui has been placed on behalf of Rūnanga o Ōtākou and Kāi Tahu ki Tuawhenua Kāhui, and a blessing was held at the site yesterday.
The man’s death will be referred to the coroner.
