Ever come across aircraft wreckage in the bush?

A few years ago we were just downstream of Mangatoatoa Hut in the Ureweras. We were passing through a very small clearing, not much more than an opening in the canopy, when someone said "I think there has been a plane crash here". He was looking at a small wooden cross nailed to a tree with a name scratched on it. I am not sure if it was before or afterwards but we noticed hanging on a nail on the side of the hut was a piece of aluminium trim, the teardrop shape of the helicopter door. When I got home I did a search on the internet and found the report for a crash just below Mangatoatoa Hut in which an overloaded helecopter had crashed. The 2 passengers survived but the pilot was killed. Then at the end of the report it stated that all the wreckage was recovered, except for a piece of door trim, which was never found.

There was an interesting item on TV about a family who were searching for a specific plane wreck in Fiordland, not sure if there was a family connection for them. It looked like mission impossible - the bush was so vast and dense. Apparently there are quite a few plane wrecks in there that have never been found.I wonder if they ever found it.
