I had a leak in pipe and had to take out a section of plasterboard,
whats the best way to make a join at the green line so it doesnt crack
at a later date.
Should I just leave a gap and fill or use some tape then fill?

If you put a batten behind the join and secure both PB edges to it it is not likely to move. Ideally you should use some tape but you are going to have to buy a large roll just to do 300mm. If you intend skimming the board with plaster you can get a self adhesive mesh type tape. If you are dry lining then a paper tape is used and you will have to feather the filler well past the join to blend it in. If you are going to re-tile then British Gypsom advice is to tile direct on the PB do not skim.

Have you got a gap behind the existing plasterboard? If so glue/screw a
noggin horizontally to the existing plasterboard that can also be used
to horizontally screw the new section plasterboard. Instead of a wooden
noggin use some plasterboard in the same way behind the existing plaster
board and overlapping so the new can be glued screwed to the same.

Are you skimming after repairing? If yes then butt up the new section
and tape.

Scrim is what you need. Self adhesive these days.
An open weave tape that you cover the joint with before plastering.

Put a bit of ply behind the joint and screw with plasterboard screws. Fill
the heads and join with decorator's caulk - you'll likely need a few goes
to get it perfect as it shrinks slightly.

Although not obvious in the image, below the green line is ply for
around 6 inches so can secure with screws along that `green` joint.
