Travel Insurance for pets to New Zealand

I am moving to New Zealand at the end of November and taking my 15 month old dog with me. She has her flights booked etc, but I can not find any insurance that will cover her whilst on this journey, although New Zealand is part of the Pet travel scheme, long haul destinations all appear to be excluded. Surely people wish to have their pet insured on this distance too, just as you would yourself, in case of lfight delays etc. I would be grateful if anyone could suggest what I could use. Thanks
