Hi Hafi

As Taffy has said, it depends where you live. Most urban areas are on mains supply, known as town water. This also applies to many of the small towns, but does vary from area to area. We are moving out to NZ next year and the small town we are going to on North Island ( 6,000 residents) does have town water. With regard to sewage, I am not so sure. Again I believe in most towns houses are connected to main sewage systems, although in rural areas cesspits are more general.

Central heating is not widespread in NZ. Most houses have a wood or coal burnet with a wetback ( water heated via a boiler behind the burner). Heat from the burner can be ducted into other rooms, but generally house temperatures are dependant on where you live. New Zealanders tend to wear extra clothing indoors during the winter. My mother lives south of Dunedin and it gets pretty cold in her house in Winter.

You can have central heating installed via radiators as in UK. The only issue here is the heating source. Natural Gas is not available on South Island, as far as I am aware. Here coal can be used to run central heating systems. It works by coal being automatic fed to a boiler via a hopper. Low Pressure bottled gas is also available, with wood burning being a widely used source of heat

On North Island it is of course warmer and there is some natural gas. However do not expect many houses to have central heating, as we know it, already installed. When we were their last year we looked at several new houses and houses under construction and spoke to a couple of building firms. Wood and coal ( solid fule) burners are still the most widely used form of heating.

Well that is the limits of my knowledge exhausted ( based on a great deal of research). I am sure kiwi readers of this website will correct me where I am wrong.

Where exactly are you going to live? I have travelled most of NZ over the years may be able to throw some more light on the area of your choice. Always available to help others and good luck.
