The capital raising will see North Shore-based boutique fund manager Pie Funds take a 6.6 per cent stake in the craft brewer.
Pie Funds chief executive Mike Taylor said his firm was bullish on the craft beer market's prospects.
"The craft beer industry is growing very strongly - the channel is growing at 35 per cent per annum," Taylor said. "At the expense of large, well-known brands like Heineken, the craft brewers are taking over the industry."
He said Moa had strong growth potential, particularly through its move into distributing other craft beer brands.
"They've narrowed the loss in the business," Taylor said. "They're continuing to grow the top line."
Moa did not name the other institutional investor that will participate in the placement.
"The total placements represent a stake of 7.3 per cent in the enlarged share capital of Moa and the pricing represents a discount of 6.4 per cent to the volume weighted average price (VWAP) of Moa over the last 60 trading days," the company said.
Moa said the new capital would be used to expand its sales team in New Zealand and overseas, while also providing additional working capital for its core business and new initiatives such as the ParrotDog tie-up.
Existing Moa shareholders will be able to invest at the same price as the institutional investors through a non-renounceable rights issue to raise $1.3m, the company added.
"The rights issue will allow shareholders to take up one new share for every 30 held on the record date, which will be announced shortly."
Moa said institutional investors and founding shareholders, The Business Bakery and its associates and Allan Scott Wines and Estates, had committed to take up their pro rata holdings to 100 per cent underwrite the rights issue.
Miro Capital Advisory is the lead manager of the placement and rights issue.
It's been a bumpy ride for Moa shareholders since the firm's 2012 listing but the company's annual result, reported in April, showed signs of improvement.
The company narrowed its loss to $2.9 million from $5.6m a year earlier, while boosting volumes and cutting operating costs.
Moa shares, which have gained 188 per cent over the past year, opened at 85c today, still well below their IPO price of $1.25.
