Kennedy claimed the company was still seeing strong demand, and "growth in our order book", supported by the Government's subsidies for electric vehicles.
"While we have hit pause for now, we have a number of significant strategic initiatives to progress this year. We believe the market will further consolidate in the coming years and Armstrong's intends to play a lead role during this period," Kennedy said.
"When we come back to market, we look forward to being able to engage with potential investors in person – something we had to manage virtually this time."
Founded in Christchurch in 1993, Armstrong's operates 15 dealerships in Dunedin, Christchurch, Wellington and Auckland, selling 16 global automotive brands.
The company has said it had grown to annual revenue of close to half a billion dollars, while according to the AFR prospective investors were told it expected to record turnover of almost $550m in the 2022 financial year, rising to $627m in 2023, with earnings rising from $37.5m and $45.6m across the forecast period.
Armstrong had indicated he intended to retain a majority stake in the company.
