WATCH: Martin Aircraft jetpack fly over a golf course:
Martin plans to use the Series 1 Jetpack for capability demonstrations to potential customers in 2017, boosting sales and securing further funding for design, development and certification of the Series 2 Jetpack next year, it said.
Last August, Martin reported an annual loss of $5.2 million. The 17-year-old company has said it hopes to make first deliveries in the second half of this year, with a personal jetpack available from the second quarter of 2017.
The machine can be flown by a pilot or remote control and its potential uses include search and rescue, military, recreational, and commercial applications. It can fly for up to 30 minutes at a maximum speed of 74 kilometres an hour at an altitude of 1,000 metres.
The Christchurch-based company raised $28 million in an initial public offering on the Australian Securities Exchange in February 2015, which saw Chinese entrepreneurial investor KuangChi Science become the largest shareholder with 22.7 per cent.
Martin Aircraft shares last traded at 46 Australian cents, below their 60 Australian cents listing price but ahead of the 40 Australian cents they were sold at in the initial public offering. The stock has fallen 37 per cent this year.
