My Food Bag Group said it had received notice "overnight" that chief executive Kevin Bowler intended to resign.
Bowler joined My Food Bag in June 2018 as its first independent CEO and had overseen a period of significant change, the meal kit company said.
Chair Tony Carter said Bowler had successfully led the business through the Covid-19 pandemic, which delivered several significant challenges, such as heightened health and safety risks, supply chain disruptions, rapid periods of growth and high inflation.
"It has been a challenging time for My Food Bag and despite this, with Kevin's leadership, the business has performed well, transitioned to a publicly listed company and is investing for the future," Carter said.
"During Mr Bowler's tenure, the business virtually tripled its earnings, took control of national operations from third parties, opened two new assembly facilities in Auckland and Christchurch, and broadened its offering to customers by adding recipe choice, made meals and its grocery options via the kitchen."
