PDL 44 ceiling rose. 5 terminals, rated 5 amps maximum. The standard NZ ceiling connection for a pendant light fitting. A short piece of flexible cable and a matching PDL 26 lampholder and you have the standard light fitting for most 1970s NZ homes. If you are really bent on recreating Kiwiana then you should also use a PDL 49 shade….
The basic light fitting does not get any better – designed in Christchurch and world famous in NZ.
