Moving to NZ from states and looking for recommendations

I’m moving to Wellington in a few months from the US. I have a spouse and two children (still in car seats at least 3 more years). We are looking for a fuel efficient vehicle that will have ample space for a family and be able to transport mountain bikes. I have noticed there are a lot of different cars than what we are used to in the US. Does anyone have a car/van/suv you can recommend for our family? I have been looking on trademe but I’m getting overwhelmed easily and not sure how to tell what is a good car. Also what does NZ new mean? Thanks in advance!
