In April the crippled helicopter was lifted off the Wellington Hospital rooftop helipad by crane and carried back to Hawke's Bay on a road transporter.
The Squirrel was replaced by the bigger BK117 in 2010 because it had been struggling with weight performance issues.
The payload was becoming increasingly difficult in certain missions, such as patients weighing over 85kg and at higher altitudes.
Each year the rescue helicopter service assists in over 300 missions within Hawke's Bay.
The Trust is supported by generous contributions and fundraising from individuals and organisations in the region.
The Lowe Corporation Rescue Helicopter crew was called into action yesterday at about 12pm after a 31-year-old man fell from his horse while riding on the road at Tuai, near Lake Waikaremonana.
He suffered shoulder and rib injuries and was airlifted to Hawke's Bay Hospital for further treatment.
