NZX says rising geo-political risks and the uncertainties of New Zealand's general election and the forming of the next government may temporarily depress the number of companies deciding to list.
But the chief executive, Tim Bennett, says the growing flow of funds into KiwiSaver accounts and the large number of private companies wanting to list should ensure a steady stream of new listings.
On Monday, the stock exchange operator said its first-half net profit rose 8.3 percent, reflecting strong growth in its capital markets businesses and its agri information arm.
NZX's net profit for the six months ended March of 7 million dollars was achieved on a near 3 percent rise in revenue to 31.2 million.
A key factor in the profit increase was that the same six months last year included a write-down in the value of the Australia-based Clear Grain Exchange.
Mr Bennett said any drag on the listings pipeline was likely to be temporary.
