Outside of a laboratory, it isn't easy to distinguish between pectin and
tannin hazes in perry.
To fix the problem, you can try pectinase as you suggested. Give it days
or weeks at room temperature to show an effect though, but even so it
may not work.
If there's no change after that (assuming fermentation is quite finished
- is it?), you could try cold shock, if you can get it into a fridge or
if we get a cold snap outdoors. A couple of cycles of cold / warm may
help to bring it down.
Finally you might try fining. A two part fining from a home-winemaking
shop is probably best because then there's less danger of overfining and
stabilising the haze indefinitely. Ideally you should do trial finings
first, but on such small volumes it's not really practical.
I'm afraid perries are quite often like this. It goes with the territory.
