Should you have not been able to use a national visa issued by the German Embassy Wellington due to COVID-19 and the resulting entry restrictions into Germany (for a period from March until June 2020), a new visa may be issued provided the purpose of stay and location have not changed. This will be possible until 31 December 2020.
You will have to provide new documents relevant to the changes of dates of travel (e. g. contracts, insurances, flights etc.)
Make sure that you apply for the visa that corresponds to the actual purpose of your stay :
All applications must be lodged in person at the Embassy in Wellington by prior appointment using our online booking appointment system. Please note that you can not apply more than 3 months before your entry to Germany.
