Property Insurance

I have some investment property in New Zealand which is in the process of being sold. Due to some recent periods where the properties have been untenanted, some unpleasant individuals have damaged the properties. Claims have been lodged with the insurance company and will be processed and this is to be included in the contract re: repair work to be undertaken.

I am now in the precarious position where the insurance company have elected to cancel the policy due to the claims history (several claims made due to malicious damage occurring-stolen hot water system, internal and external damage to property etc). I have negotiated with the insurance company but to no avail and other insurance companies are not interested (including insurance brokers).  Can anyone please provide any miracle options which I am yet to explore so I can protect these assets until the sale is finalised?

Kind regards,

Gary

Cant help sorry, but i am curious - where exactly in NZ is it
