What are the chances of a review if a persons visitor visa?
The decline letter from Immigration NZ will state the grounds on which your visa application was declined. Address the concerns raised in any subsequent application and you will have a fair chance of successfully getting your visa. From my experience of 15 years in the NZ migration industry I have found Immigration NZ to be a very reasonable organisation and works on the tenets of fairness and natural justice. So if an application ticks all the boxes then your chances will be very good. Since immigration is a complex legal subject, it is advisable to seek the services of a professional like a licensed immigration adviser. All the best.
