Don't let that hold you back. I just did my first 2 switches this weekend, where I needed to pull through a neutral. At first it seemed liked a daunting task, but it really is easy.
1. I had my old telkom line taken down (since having vumatel), so used that wire as drop wire, eg. for pulling through 1st time.
2. I don't see it in your pic, but there should be an earth wire screwed to the metal holder. You going to use that.
3. There should be a neutral at the light.
So what you do is, open up the light switch like in your pic.
Next, also open up the light where you replace the bulb, but go further, where you unscrew the whole light from the ceiling, so that you can see all the wires, those that go to the DB board.
At the switch, unscrew the earth, and put the drop cable through it. I then use that brown tape, to cover it and keep it together.
Pull the neutral from the switch to the light. So now you have the drop cable with the 4 live cables in the conduit.
Then measure your earth cable, cut the new neutral to the same length and add it to the cable. Again, put it through the hole that is attached to the earth (that is where the screw go through at the switch). Put tape over again. Pull both the neatral and earth back to the switch. Connect the neutral on both sides, and tada you have a neutral with minimum effort.
