Steven Joyce: former Finance Minister on the origins of the emergency alert system - Matt Heath & Tyler Adams Afternoons

Phones across the nation blared mobile emergency alerts at 6:30am this morning - following on from yesterday afternoon's warnings to stay away from the ocean following the Russia quake. 

The alert system is designed to keep people safe, but it's raised concerns after people reported receiving repeated alerts through today and Civil Defence is looking into the glitch.

Former National MP Steven Joyce acknowledged there was always a risk of fatigue when it came to the system.
