Question

Why are there no snakes in New Zealand?

Answer 1

Hint: Snakes can be found in a variety of environments, including water, woodlands, deserts, and grasslands. Snakes, like the majority of reptiles, are ectotherms, meaning they must maintain their own body temperature. Snakes warm up by basking in the sun and then cool down by moving to cooler environments.

Complete answer:
Except for a number of snakes kept in zoos in the major cities, New Zealand is snake-free. To begin with, New Zealand is geographically separated from the rest of the world. Between New Zealand and the nearest significant landmass is almost a thousand kilometres of ocean. There are no snake species capable of travelling so far across water.
Second, the New Zealand government is working hard to keep New Zealand snake-free. This means that if snakes get into the nation via shipping containers or other means, they are immediately tracked down and captured. Snakes would annihilate most of New Zealand's endangered native animals if they were imported.
Also in New Zealand, having snakes of any type is illegal.
Snakes of any sort are prohibited under the Hazardous Substances New Organisms Act 1996, Second Schedule.
Snakes can enter the country in a variety of methods, including:
Inadvertently - hidden in imported products, such as banana pallets/crates, or in containers;
A sea snake is occasionally found washed up on a beach; and smuggling - snakes have been smuggled into New Zealand by a few persons. They are tried and sentenced to prison since having a snake is a criminal offence in New Zealand.

Note:
Not only was NZ free of snakes, but it was also free of most predators, including animals. At one point, there were only birds, frogs, and lizards. The species, such as the kiwi bird, had such a safe isolated life on the islands for millions of years that most of them lost their ability to fly.
However, as humanity discovered it, this paradise began to change. Humans might hunt the native birds in the same way that they would pick apples. In the 14th century, the first rats (kiore) were transported in Polynesian boats, and the destruction began.
