I don't know how hot it gets in Auckland in summer (I've only ever been to NZ in winter!) but if it gets hot, then go for a pale colour. Dark roofs should be kept for cold places!

Silver.

New house build.I need a idea for colour matching trim colour on my house. Out side is corrogated iron walls ánd roof in greyfriars,300mm square posts,front and back are in black,inside is spanish white,trim,walls and ceiling in semi gloss. What I am looking for is a colour for the barge boards,front and rear only,rear wood door surround,internal doors (only two,bedroom and bathroom). Was thinking a gutsy orange? Awaiting your views/thoughts

Personally , I think the main colour is fine , the crisp white on the poles and most of the terrace is fine -- the two different 'sandy khahki' shades ( the window surrounds , and the planter ) looks out of date . I'd do both of them in charcoal , as well as the terrace base board and the upstairs downpipes . It looks like the barge board and the veranda are already a charcoal -- if not , then darken them up too . The mid grey on the steps etc is fine as is , it's hard to see in the photos but the front door looks like it might be a nice solid wooden one -- again , thats fine to me , but I'd do the door surround in a crisp white to make it more noticeable . The other brighter option would be to do the window surrounds , the door surround , the top barge board including the gables , the terrace base and probably the terrace top rail -- all in a bright sunshine yellow !
