Mayson said the amendment would allow for more flexibility in finding global talent for the company's board.
The meeting was held at Aircraft's base in Christchurch where the change was supported by 87 per cent of those who voted.
The change means that all directors of the company could be from out of New Zealand.
The company said last month that Martin Aircraft only had operating funds to the end of August, and would require further funding to complete its test programme and to find commercial opportunities.
In a statement to the ASX, Martin Aircraft said it had assumed that where required, it would be able to use cash from KCS, however, it had since discovered this funding was tied up and would not be available.
"The company is investigating further options to secure these funds," it said. KCS has yet to announce if, and when, it would provide further funding.
Martin Aircraft listed on the Australian Stock Exchange two years ago hoping the move would bring in new investors.
Since it listed, its share price has fallen from A$1.75 in March 2015 to A5c a share today.
Commercialisation of the Martin Jetpack began in 1998 by its inventor Glenn Martin who has since cut ties with the company.
