Did it not evolve flightless birds because they had few mammal predators but did the Earth, in a Gaia theory way, produce a land with special and unique life forms.
Different from those found on other islands to give life a chance no matter what catastrophe struck or arrived on the island of New Zealand or planet Earth?
There are around forty species of flightless birds in the world today, with New Zealand being home to the greatest number of these species. Among New Zealand’s flightless birds are the kiwi, takahe, kakapo and several species of penguins. It is thought that these New Zealand birds never developed the ability to fly because they had no land-based predators to escape from – until the arrival of human beings. Isolated from the rest of the world for millions of years, these flightless birds adapted to their environment in a way that would most benefit them.

Or if looking at it from a 'morphic field' or that DNA is influenced by the electromagnetic environment around it - did the natural energy of New Zealand mean that predator mammals would not be created but lots of flightless birds would?
