New Zealand is home to one of the largest Korean communities in the Pacific, concentrated primarily in Auckland's North Shore suburbs. South Korean nationals are among the top source countries for New Zealand residence visas, arriving through skilled migrant and employer-assisted pathways. If you are a Korean national living in New Zealand and thinking about citizenship, this guide covers the pathway, the dual citizenship rules, and what you need to consider before applying.
The pathway: work visa to residence to citizenship
There is no shortcut from a Korean passport to NZ citizenship. The standard route involves three stages:
Stage 1: Work or student visa
Many Korean nationals arrive on an Accredited Employer Work Visa (AEWV), a student visa followed by a post-study work visa, or an employer-supported Essential Skills visa. This stage typically lasts 1–3 years while building an employment and presence record in New Zealand.
Stage 2: Residence visa
Common residence pathways for Korean nationals include the Skilled Migrant Category (SMC), a partner-based residence visa if your spouse is a resident or citizen, or the 2021 Resident Visa (now closed to new applications but already granted to many Koreans in NZ). Processing times vary from 6 to 18 months depending on the category and current demand.
Stage 3: Citizenship by grant
After holding a residence class visa for 5 years and meeting the physical presence requirements — at least 1,350 days in New Zealand over those 5 years, with at least 240 days in each 12-month period — you can apply for citizenship. Use our eligibility calculator to find your exact date.
Common visa routes for Korean nationals
| Visa route | Typical timeline to residence |
|---|---|
| Skilled Migrant Category (SMC) | 1–2 years from EOI to residence |
| 2021 Resident Visa (RV2021) | Already granted (applications closed) |
| Partner of NZ citizen/resident | 6–12 months for residence |
| Student visa to post-study to SMC | 3–5 years total |
| Accredited Employer Work Visa (AEWV) to SMC | 2–3 years |
Dual citizenship: South Korea does not allow it
This is the most critical consideration for Korean nationals. Under South Korea's Nationality Act, a Korean citizen who voluntarily acquires the citizenship of another country loses their Korean nationality. Dual citizenship is not permitted for this group.
- •You cannot hold both a Korean passport and a New Zealand passport simultaneously
- •After acquiring NZ citizenship, you are required to renounce your Korean citizenship
- •Renunciation is processed through the Korean Consulate-General in Auckland or the Embassy in Wellington
- •Very limited exceptions exist — primarily for those who acquire foreign citizenship at age 65 or older while residing abroad
South Korea does not have an equivalent to India's OCI card. Once you renounce Korean citizenship, you travel to South Korea as a foreign national. New Zealand passport holders can enter South Korea visa-free for up to 90 days under the bilateral visa waiver arrangement. For details on how NZ handles dual citizenship from its side, see our guide on dual citizenship in New Zealand.
Military service: an important consideration for Korean men
South Korea requires most male citizens to complete mandatory military service (typically 18–21 months depending on the branch). The interaction between military service obligations and renouncing Korean citizenship is complex and depends on individual circumstances — including your year of birth, whether you have already completed service, and whether you have an exemption.
If you are a Korean man who has not yet completed military service, you should contact the Korean Consulate-General in Auckland before taking any steps toward NZ citizenship. Renouncing Korean nationality without fulfilling military obligations may have consequences under Korean law. This is not legal advice — verify your specific situation directly with Korean authorities.
Presence requirements and travel to Korea
Many Korean residents in NZ travel home to visit family, especially during Korean national holidays. The citizenship presence rules apply to all time outside New Zealand, regardless of destination:
Total days in NZ required over 5 years
Minimum days in NZ per 12-month period
This means you can be absent for up to 125 days per year on average. A typical 2–3 week trip to Korea once or twice a year is manageable, but extended stays or multiple trips per year will reduce your travel budget quickly. See our guide on counting presence days for the detailed rules on how days are counted.
Realistic timeline
- Years 1–2:Arrive on work or student visa, build employment record
- Year 2–3:Apply for residence visa (SMC, partner, or other category)
- Year 3–4:Residence visa granted — 5-year citizenship clock starts
- Year 8–9:Eligible to apply for citizenship (if presence requirements met)
- Year 9–10:Citizenship granted, ceremony attended, NZ passport obtained, Korean citizenship renounced
Korean nationals who arrived on the 2021 Resident Visa may have a shorter overall timeline if they had been living in NZ for several years before the visa was granted. Use our calculator to find your specific eligibility date.
Tips for Korean nationals
- •Start tracking your travel days from the date your residence visa was granted — not from when you first arrived in NZ
- •If you are a Korean man with outstanding military service obligations, seek advice from the Korean Consulate-General before applying for NZ citizenship
- •Budget time for the Korean citizenship renunciation process after your NZ ceremony
- •Gather your required documents well in advance, including a police clearance certificate from South Korea
- •Check whether you need a Permanent Resident Visa before applying (see our resident vs permanent resident guide)
Frequently asked questions
Can I hold both South Korean and New Zealand citizenship?
Generally, no. South Korea's Nationality Act does not permit dual citizenship for those who voluntarily acquire a foreign nationality. If you become a New Zealand citizen, you are expected to renounce your Korean citizenship. There are very limited exceptions — for example, those aged 65 or older when acquiring foreign citizenship abroad. Check with the Korean Consulate-General in Auckland for your specific situation.
Does becoming an NZ citizen affect my Korean military service obligation?
This is an important consideration for Korean men. South Korea requires most male citizens to complete mandatory military service. If you renounce Korean citizenship before fulfilling your military service obligation, there may be restrictions or penalties under Korean law. You should verify your individual obligations with the Korean Consulate-General in Auckland before proceeding with NZ citizenship if you have not yet completed military service.
Can I still visit South Korea after becoming an NZ citizen?
Yes. Former Korean nationals travelling to South Korea on a New Zealand passport can enter visa-free for up to 90 days under the NZ–Korea visa waiver agreement. For longer stays or work, you would need an appropriate Korean visa. Unlike India's OCI card, South Korea does not have a formal scheme that gives former citizens special residency or work rights.
How long is the full process from Korea to NZ citizenship?
The typical timeline for Korean nationals is 7–10 years: 1–3 years on a work or student visa, 6–18 months to obtain a residence visa, then 5 years meeting the presence requirements. Those who arrived via the 2021 Resident Visa may have a shorter overall wait depending on how long they had been in NZ before their visa was granted.
