The NZX is now back in operation after a technical glitch this morning kept investors in the dark with no market announcements being published on the stock exchange operator's website and Reuters and Bloomberg services not showing trading action.
The stock exchange did not publish any new market announcements on its public website throughout the morning, due to technical issues though trading was open, an NZX spokeswoman said.
It was unclear whether that was behind Reuters and Bloomberg terminals not showing any trading action, and if that extends to IRESS products.
In a formal announcement at 11am, the NZX confirmed it was currently experiencing difficulty with its market data feed.
"The practical implication is NZX is unable to provide market announcements or price information to the wider market," it said in a statement.
