Nosh Food Market co-founder and former chief executive Clinton Beuvink has left the specialty grocery group and his position has been filled by chief financial officer Hayden Syers.
Beuvink had his last day on Friday, some seven years after the first Nosh store opened its doors.
He could not be reached for comment but a Nosh spokeswoman said he resigned for personal reasons.
Syers, who joined the company as CFO in March and became a director of Nosh Management last month, is the firm's new chief executive.
Before joining Nosh, Syers was chief operating officer at NZ Mint, according to his LinkedIn profile.
