Best upcoming location in Wellington

[newbienz]

Hi there

I am intending to buy a house in Wellington in the next few months
My budget is 600 to 700k
I am working in the software sector and my wife is a free lancer working from home
We are both in our late 20's and this will b our first investment

I prefer to travel to work in the CBD by bus so the area should be well connected by bus service

We are looking for a 2 or 3 bedroom house preferably in the suburbs (about 180 to 200 sqm) so that we get a better value for money. The houses should be newly built and preferably not more then 10 years old

So which area should I be looking for as I prefer to stay in a comparatively high income locality ?
I had thought of Whitby in Porirua as its an upcoming development and houses are being sold at my median price so logically the residents would be in the higher income bracket
Any other recommendations?

Thanks for advising
