KEY POINTS:
NZ First MP Ron Mark wants screening of all passengers on small planes, saying yesterday's hijacking bid showed the failure to do so was a weak link in aviation security measures.
Under present laws, although it is prohibited to carry sharp objects or weapons in hand luggage, passengers on aircraft carrying fewer than 90 people do not have to be screened.
Mr Mark said: "This just demonstrates how serious one incident can be, and all for the lack of what? Screening procedures? It's a hell of a lot more inconvenient to have an aircraft go through the roof of your house, or have the whole airport shut down just because of the lack of screening at an airport in Blenheim."
Transport Minister Annette King said she was expecting reports about the incident from police and aviation security early next week, and would be guided by any recommendations.
But she said present security met international standards including those of the US, and it was important not to overreact to one incident.
"People can be reassured we will take notice of any advice we are given by our security people.
"But it's probably more dangerous for people driving in a car to the small provincial airports than it is actually getting on the planes, given the accident rate on roads."
Blenheim Mayor Alistair Sowman said he did not believe tighter security measures at his town's airport were warranted.
