Like LimeSlice said ISOFIX doesn't mean we get to ERF We also can't share international standards as NZ can so it will still be illegal to use an imported seat. The Aust approved seats released will have the same weight limits for rear-facing as the one we have now.

Cazz88, I'm not sure NZ actually manufacture too many, if any seats themselves. They share our standard and they are also allowed to share the standards of some other countries therefore have access to a wider variety of seats IYKWIM. So importing from NZ doesn't necessarily mean the standard that seat will have is similar to ours. It could be European/UK or US standard approved.
