Lynnell Greer: Department of Conservation Visitor Advice Manager on the Great Walk booking system's crashes - Heather du Plessis-Allan Drive

The Department of Conservation has blamed a 'function issue' for the repeated crashes of the booking system for the Milford Track Great Walk.

Thousands of trampers were left frustrated on Wednesday, spending up to an hour trying to log onto the booking system for the track after the web-page glitched.

DOC's Visitor Advice Manager, Lynnell Greer says that they will ensure the system is fully functional before the next round of Great Walks open.

She says the issue wasn't picked up in testing, and they will now be asking their IT vendor why that was.
