I am installing some architrave power sockets into a garage ceiling, so I have flexibility to move light fixtures around.

Country is New Zealand, and the line voltage specs are 230V AC 50 HZ.

I have run 1.5mm2 cable, but there are points where I want one socket to have two wires, an incoming and an outgoing.

I have been using the correct size ferrule, but now I want to put two wires under one screw.

Do I put two wires into one larger ferrule? enter image description here

OR Do I put two ferrules under one screw? enter image description here

Wire nuts are not an option here - I could pigtail out to a three-way joiner, but that needs its own junction box.

What's the best way to do this? Extension question, what if there were more-than-two wires coming to the same point?

Batten sockets are more usual in that application.

SFAIK ferrules are not required (although this may have changed since I last looked), If you are going to use them put all the wires into a single ferrule.

1.5mm2 seems kind of skinny for outlets. (but this is a lighting circuit, not a GPO circuit, so assuming 10A breaker or smaller this is fine)

You are absolutely allowed to use those holes to join multiple wires, this is why they are 5mm diameter.
