An alleged hijacking last year prompted a review of aviation security which found some domestic flights to be at high-risk.
Asha Ali Abdille, a 34-year-old Blenheim vineyard worker, was accused of hijacking a passenger flight from Blenheim to Christchurch on February 8, 2008.
She was also charged with taking an offensive weapon onto an aircraft and four charges, two of which relate to attacks on the pilots, of wounding with reckless disregard for safety.
The trial has been set down for two weeks in September with two days of pre-trial arguments from June 15.
Transport Minister Steven Joyce said the review assessed risks in New Zealand's domestic aviation environment and whether current security levels were adequate.
A summary of the report, released today, said domestic flights of fewer than 90 seats with unscreened passengers and carry-on baggage were a high-risk area.
The summary said greater screening of crew and carry-on baggage would be the best way to increase security.
The cost of such screening was likely to be about $5 per passenger on each additional screened flight.
Other options included strengthening cockpit doors, security committees at airports and enhanced training and education for airport workers.
Cabinet would decide on any changes next month, Mr Joyce said.
"These are challenging and important decisions."
The two Air New Zealand pilots who stopped the alleged attempted hijack, Ross Haverfield and Dion McMillan, were honoured with the International Airline Pilots' Association Polaris Award for heroism last month.
