More than 258 tonnes of fruit has been produced over the past three years.
The winery has been a feature of the summer music scene, regularly hosting concerts.
Mr Loughlin said it was time to start a new chapter in life.
"It has been our baby for 19 years and with what I've done in the business world I've been working seven days a week, as has my wife Kathryn."
He is a professional company director involved with Zespri, Centralines, Tru-Test Corporation, Firstlight Foods NZ, Metlifecare, Port of Napier and AgResearch.
"You can only do that for so long," Mr Loughlin said.
"In the last few years we have had a few bereavements in the family. It makes you reflect on life and nobody ever died wishing they had worked harder.
"We decided it was time to enjoy ourselves and move on."
Marketing the vineyard is Bayleys Napier country/viticulture manager Glyn Rees-Jones.
"This is a superb opportunity to take on a highly regarded integrated viticulture business with a well-known and established brand," he said.
"Askerne wines have achieved a strong track record of success over 15 vintages, including three trophies and 16 gold medals."
