The pair of tiers are about 30m from the house and have armoured wire going to each point. I want to add an additional light to each pair. I have the following qns...

I hope the above is clear, please let me know if you need more info.

jig,
you should use the same cable as already in circuit, lights are wired in parallel and not series. So it's a line conductor and neutral conductor across the lamps, you'll need swa clips, glands, olives, bangos etc...
It's a part p notifiable work, if not done by registered electrician.
An electrician can issue electrical installtion certs where Building controls normally issue compliance to building controls certs.

SWA 1.5mm/sq
Gland Packs for the above.
As it is a special location, it must either be notified an inspected by BC or their agents, or by a self -certifying sparky.

Jig,
regulation general requirement are the cable to be buried in ground about 600mm where gardening or tooling of ground could take place, it needs to laid in gravel, capped and electrical indentification tape laid across the length of it.
You could clip above ground but this must be done above level of ground at a height where mechanically damaged can be caused to cable.
Don't quite understand what you mean be tiers are we talking of raised platforms or pier post as in balustrade.
As previously stated Part P(noifiable) or Reg'd electrician, is a legal requirement
