Dogs, cats and stoats are some of the Kiwis worst enemies. Many people unfortunately just don't care and don't understand the birds are a protected species, even taking a dog into these areas on a leash is illegal.
There is the Kiwi Avoidance Training that owners can take their dogs to which teaches the animals to steer clear of the birds. I don't know if I agree with the type of training which involves the use of electric collars but until someone comes up with a different method I guess this is it.
The trainers interestingly enough found that the breed of dog was found to influence the training with terrier and working breed dogs showing higher levels of avoidance from the training and non sporting dogs showing the lowest levels of avoidance.

In general I think there should be dog parks where they can have fun without a leash otherwise: leash! I am really afraid of dogs and hate it when they roam free everywhere.
I am glad to see the area and the bird are being protected. Have you ever seen the Kiwi in their habitat. Take care, enjoy your day and have a great week ahead.
