When you're doing lighting in a kitchen it's a good idea to have good directed light over the main tasks areas, cooking, dishwashing, food prep. You could achieve this with downlights directed at those areas, or track lighting where you can direct/angle each of the lights on the track. Re the pendant over sink area, would need to be at a height that ensures safety - water & electricity, not a good combo. There may be some NZ standards that you can refer to, to get the correct info.

It comes in three sizes, as well as only coming in the white. It'll be elegant over your dining table.

Everyone has some valid points and so I would also recommend moving the clock to the kitchen wall and place the wall unit under the mirror. Centre with the table with the additions of some artwork each side if the clock with wooden frames to match the clock. Find a low piece of glass or pottery or a runner to tie in the grey shades. I presume u have a grey lounge suite. Change the lighting as to what was suggested by People Space ARchitects.

My new kitchen will be light grey cabinets, white and grey stone bench tops. My current dining table is a clear glass top, black leather chairs with chrome legs/framing. I love these gold polished glass pendants for over my island bench but will they look okay with my dining suite or is it too different? I can go for the grey glass lights but they are quite opaque during the day.
