We went through this process recently and got 12 LED down lights in a living/dining area which previously had only pendants. They're wired as 3 sets of 4, one of those groups is on a dimmer. No flickering on ours.

 

 

 

FWIW initially I wanted them wired as 6 pairs but the sparky and missus went to groups of 4 - pairs would be awkward for switching because of the number of switches and faceplates required.

 

 

 

Bearing in mind that dimmers are ~$100 each the sparky's own advice was to have one group on a dimmer and live with it for a while. Recently my wife has been saying things like, THIS group would be better on the dimmer, not THAT one so I take his point.

 

 

 

That's all easily re-wired in the flush box - I can do that, but the lights will always be controlled in groups of 4 - hence my suggestion to take all your wiring to the flushbox and leave yourself the freedom to change in the future. 

 

 

 

This is the low tech cheap and easy way to do it - otherwise you are looking at IOT lights or some kind of smart lights that receive commands from a controller via the power wiring.

 

 

 

 

 

thats good advice thank you. The dining is pretty small so only having 4 which wont have dimmer, the kitchen will be Ushaped but attached only to dining room. The lounge would be 6 lights .Could do 3 sets of 3 or 2 sets of 6 and 3 .I have gone off dimmer as not that cheap and not sure i would use it much

You can buy dimmers a lot cheaper than $100. More half that price for PDL600 series ones at  https://www.electricaldirectltd.co.nz/search?query=+624TM  . You do however need to check the dimmer is compatible with the lights you buy, so you also need to buy decent lights.
