Key cautious about full screening at airports

Expensive upgrades of airport security are unlikely to fly, with Prime Minister John Key saying he will take a cautious approach.

An alleged hijacking last year prompted a review of aviation security which found unscreened passengers and carry-on baggage were a high-risk area but that the threat of terrorism was "very low".

The review said greater screening of crew and carry-on baggage would be the best way to increase security, at an estimated cost of $5 per passenger.

Other options offered by the report included strengthening cockpit doors, security committees at airports and enhanced training and education for airport workers.

Mr Key was asked about the recommendations this morning.

"Whether you want to go to full screeing at all of those 10 airports I think that's something that you'd proceed with caution on," he told reporters.

The Government is to decide on security measures next month.

Transport Minister Steven Joyce last week raised concerns about adding costs in tough economic times but said some measures, such as reinforcing cockpit doors, made sense.
