I consider things relatively OK in Chch (haha, other than ground shaking!)
Rent varies, in an average area you're looking at aourn $300-400 for a 3-bdrm, depending on section size, garaging etc and school zoning. More in better areas and vice versa. It really depends atm though, people are paying crazy prices for an undamaged rental. Outlying areas are now basically on par with city prices as demand is excessive.
Movie rental depends - we go to United Video so it's pretty cheap, I think $4 for a new release but we go for $2 Tuesdays a lot of the time.
Food is OK - we pay $120 a week for the 4 of us, but we eat pretty basically to save money. We do however shell out on takeaways once a week when I have meetings, so that's an extra $30.
Pools for kids (public) are about $3 for a preschooler and parent.
Parking was pretty good - $2.60 an hour or $12 a day in town. Obviously not needed as much anymore

pretty good public transport system, especially now they have a bus depot again.
