Formerly a natural bird sanctuary, New Zealand is the last country in the world to be inhabited by humans. A few species of bats are the only indigenous mammals to New Zealand. Other mammals arrived with the people. These include farm animals (cattle, deer, and sheep), domestic animals (dogs and cats) and pest like rats, stout and possum.
This could explain the current ration of animals (95%) to humans (5%) - one of the lowest humans to animal ratios in the world. New Zealand is home to nearly 4.8 million people and over 30 million sheep, 10 million cattle, and nearly 2 million farmed deer.
Don't let the country's small size fool you. New Zealand animals also hold many world records including largest, smallest, heaviest, oldest and a few surprises.
