저도 관심있어 알아보고 있는 중인데요(더 나은 방법이 있을지도 모르겠지만)
부모비자는 3년간 18개월(미리 당겨 쓰던, 1년에 6개월씩만 쓰던 관계없이)이고 이전 비자와는 관계없이 그때부터 새로 시작이니까 일반 체류연장 비자(최장 9개월) 사용후 부모비자를 신청하면 뉴질랜드 체류 기간을 최대한 길게 사용할 수 있을것 같긴한데요. 더 좋은 방법이 있을지도 모르니까 이민성에 알아보라는 분도 계시고... 에고 나이많으신 부모님 영주권 받을때까지 한국 들락날락 하시도록 해야하니...
Multiple entry visitor visa for parents and grandparents of New Zealand citizens/residents
If you have family members in New Zealand and you wish to visit them, you may apply for a visitor visa under normal visitor instructions to allow you to travel to New Zealand, or you may travel to New Zealand visa-free if you are a ‘visa waiver visitor’.
However, if you are the parent or grandparent of a New Zealand citizen or resident you may like to have the flexibility of a multiple entry visa, to allow you to visit your child or grandchild several times over a three-year period. To do this, you may apply for a visitor visa under the parent and grandparent multiple entry visitor visa (see V3.110 in our operational manual).
To be eligible for a visa under these immigration instructions, you must apply from outside New Zealand, and you will need to complete full medicals and meet normal character requirements (you may include your partner in the application but not your children). Your New Zealand sponsor* will need to complete the Sponsorship for Temporary Entry (INZ 1025) PDF and must guarantee to meet the cost of your maintenance, accommodation, repatriation (if necessary) and healthcare costs (if required).
If the application is approved you will be granted a three-year multiple entry visitor visa, authorising stay for a visit of six months from your date of arrival. You will not be able to extend the visa, however you will be able to enter and leave New Zealand during the validity of your visa, as long as you do not remain in New Zealand for more than 18 months during the validity of the visa.
Further applications under these immigration instructions:
A further visa will not normally be granted under these instructions within three years of the date that the most recent visa was granted.
If you have previously been granted a visa under these instructions and your sponsor was not in New Zealand during the period(s) of your visit(s) to New Zealand, or if you exceeded the 18-month maximum stay on your previous visa, you will not normally be eligible for a subsequent multiple entry visitor visa under these instructions.
*Notes:
The sponsor must be your child or grandchild aged 17 years or older, or the New Zealand parent of your child or grandchild.
Evidence of the family relationship(s) must be provided.
The sponsor may sponsor only one person or one family unit (principal applicant and their partner) at one time.
