Currently in New Zealand, the law doesn't actually give any automatic rights to what the law describes as the "intending parents". So, when born, the child's parents, in law, are the surrogate and their partner, and the intending parents then need to go through the full and dense adoption process. The child itself may have come from the implanted embryo that was made, if you will, from the intending parents' egg and sperm and it may bear no genetic similarity to the surrogate, but still the intending parents are not regarded as the parents until they have gone through that full adoption process.
