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.

The timber island coming off the kitchen bench!

I love our island bench in the mornings - I have 4 kids, 3 of which are teenagers, and the morning rush to get out to school is chaotic. The kids all come through to the kitchen at different times for their breakfast, which I have set up on the bench, and they can just grab what they want, sit on a barstool and gobble it quick. Then it's just the kitchen bench that needs a good clean after breakfast. don't have to worry with the dining table. Evening meals are a different story though, I believe families should sit down together at the dining room table.
