New Zealand stock exchange operator NZX halted all trading saying most platforms would not resume until Tuesday's open after traders experienced connectivity issues.
"Following today's network connectivity issue and consultation with cash market trading participants, NZX has determined not to reopen the cash markets for trading today," the company said this afternoon in Wellington.
"The cash markets will open to a normal trading timetable tomorrow."
NZX halted trading on its main board and debt markets at about 4.10pm on Monday- 50 minutes before the scheduled close - citing connectivity issues.
It said its vendor had identified the root cause of the problem but didn't give any further details.
