We fly out in just over 2 weeks and am organising car hire this week. We have 4 children ages 9,8,4&2 Currently we are using backless booster seats for the older 2, a highback booster for our 4 year old with the seatbelt and a child stage 1/2 car seat with 5 point harness and has a top tether as can be used with isofix points.
Am i right in assuming that we can't use any of them when we arrive and have to buy 4 new seats as they don't have the as nzs mark on them?
Its no insignificant cost to replace them all 😞
Do we definitely have to?
Any advice you can offer would be welcome
