About Us

The Missing Wingman Trust (RNZAF) is a registered charity in New Zealand which supports the Royal New Zealand Air Force family. It is the only charity in New Zealand that supports our air force families when someone is killed, wounded, injured or becomes ill, whether in New Zealand or overseas.


The charity was formed in 2010 to support our Air Force family and remember those we lost. Importantly, it doesn’t just help when a serviceperson is in need, but when any member of that person's family is killed, injured, wounded or ill, because sometimes it’s the death of a partner or illness of a child that can put our families under the most pressure. Since it's inception we’ve spent thousands supporting our Air Force families: assisting with medical expenses, repairing homes, providing scholarships, and providing support in times of grief.

The trust board is comprised of military and civilian personnel, including Judy Bailey, whose father was Chief of the Air Force in the 1960's. The Trust was chaired by former Defence Chief, Air Marshal Sir Bruce Ferguson until 2021. Currently the Trust Chair is WGCDR Ron Thacker. You can read more about our trustees below.

Steve Gregory

Steve Gregory was a founding member of the Missing Wingman Trust in 2010. His involvement followed the death of his son, Flying Officer Dan Gregory in the ANZAC Day tragedy of that same year that killed three aircrew and seriously injured a fourth when their Iroquois helicopter crashed into the hills near Pukerua Bay, north of Wellington while on their way to take part in a ceremonial fly past in the Capitol.


Although he has not served himself, Steve comes from an RNZAF family, his father Keith from Dunedin flew in Bomber Command during World War II and took part in a series of raids against the German battleship Tirpitz in 1942. He was shot down on one of these raids over Norway and survived to spend the rest of the war in various prisoner of war camps. Steve's Uncle Harvey also flew in Coastal Command during that same conflict, based on the South Coast of the UK.


Steve has been active in the insurance industry and is also a keen sportsman. He brings a personal, non-service perspective to the Trust and feels a huge amount of pride in the good work it has done for the families of affected air force families over the past 10 years.
