The mother of one of nine people who died in a skydiving crash at Fox Glacier in 2010 says the introduction of restraints in skydiving aeroplanes is too little, too late.
The issue was raised during an inquest into the deaths.
The inquest was told that if the passengers had been wearing restraints, they would not have tumbled to the back of the aircraft on take-off, causing it to suddenly pitch and crash.
The industry is now starting to introduce the restraints in anticipation of a rule change being recommended by the coroner.
But Karen Bourke, whose son Glenn, 18, died in the crash, says the Civil Aviation Authority was recommending their use as early as 2003.
