Pressure for real changes at the NZX

The Financial Markets Authority's reviewed the stock exchange ... after multiple major issues and outages last year -- including D-DOS attacks in August.

It's criticised the exchange's technology, but expressed confidence it will make improvements.

Authority chief executive Rob Everett says some of the NZX's crisis management planning and procedures were too basic.

He says the NZX has been told it needs to make changes quickly.

Everett says confidence in the stock exchange is crucial.
