In a death notice Wadsley was remembered as the "dearly loved husband" of his wife and "adored dad" of his two daughters.
A man who was at the beach called it a "sobering end" to a day out on the water.
Another man who was at the beach said in a post on the New Zealand Kitesurfing Facebook page that about 15 to 20 kite surfers were out on the water near where the incident happened.
When the Auckland Westpac Rescue Helicopter arrived the man was having CPR performed on him, rescue helicopter spokesman Lincoln Davies said.
"Medical intervention was attempted but unfortunately the man died," he said.
"Sadly the man was deceased when the crew arrived."
Police said a member of the public found the man on the beach.
"It is believed he had been out kitesurfing," police said.
