You will need to clamp the cable but a car scrap yard will probably
have an old accelerator or clutch foot pedal which you could use at
one end and fabricate a simple bracket at the other.

Or the same clutch pedal mechanism, but hydraulic.

Those ideas would be better engineering, but it needs to be something
really simple to fix without any tools by an average person, e.g. like
a cord through pulleys. In the past, going without a flush for a month
leaves the toilet rather messy!

Here's a picture of the toilet building, which is not typical of
toilets in NZ but I've seen similar in mountainous areas, which this
is.
