Shares in the listed software firm, Diligent Board Member Services have risen 2% after the former boss of the stock exchange, Mark Weldon, joined the board.
The New York-based firm's software helps company boards keep track of their documents online, and it generates its income from annual subscriptions for the software.
Diligent's chief executive Alex Sodi says he wants to tap Mr Weldon's success in expanding earnings at the NZX.
