Fearing he could be trapped between his yacht and the rocks, Mr Hutchings grabbed his bag and liferaft and swam for about 10 minutes to shore.
"I was extremely lucky it was low tide," he said.
Mr Hutchings said he would organise a team to salvage Glissade, but bad weather could hamper the recovery efforts.
He estimated there would be about 45 litres of diesel on board.
St John flight intensive care paramedic Paul Davis said the NEST helicopter answered a distress call about the yacht around 4.50am on Saturday.
It took just under an hour to locate Mr Hutchings, who had abandoned his yacht and swum a short distance to a steep rocky shoreline, where he was perched on a vertical cliff.
He was wearing his survival suit and was uninjured.
Mr Davis winched him on to the helicopter, which then returned to Whangarei.
"He wasn't injured but quite shaken up.
"He was given a hot shower and a hot drink before his family picked him up."
Mr Davis said since the tide was coming in when Mr Hutchings was rescued, he expected the yacht would have been hammered against the rocks.
Northland Regional Council deputy harbourmaster Chidambaram Surendran said the little amount of diesel was likely to evaporate, posing little danger to the environment.
He said a vessel sailing nearby on Saturday afternoon reported some debris believed to be from Glissade.
"There are no reports of any oil spill as yet so we won't be doing anything at this stage, but if further information comes to light, we'll look into it," Mr Surendran said.
