Mystery green pepper

When I was 7 living on Ngatokae in the Western province, I used to often eat a small green pepper, the shape of a kind of thin chili, cooked in a stew. It tasted amazing, but I can't find the western name for it anywhere so I can look it up and obtain some seeds.
It was not a hot pepper, there was no heat whatsoever.
Has anyone ever tried this?
I also miss petu petu and fern, and still eat pumpkin tips from my garden here in Aus.
Whenever my mum cooks a dish out of capsicum back here in Australia, the aroma reminds me of this little green pepper, but it just doesn't taste the same.

It sound like it may be what we call in the southern part of the U.S. a banana pepper. I have actually stuffed them with boudin/boudain sausage.
