You still need to get the resident visa issued, which can take time depending on what other requirements you need to meet.
If you are an investor, you will normally need to give proof of having transferred nominated funds through the banking system. If so, you have 12 months to complete that step.
In some very rare cases, there may be a need to produce other documentation before the visa is issued. If your Resident Visa is issued while you are overseas, it will be valid for entry for 12 months from the date of issue.
While you have 12 months to arrive in New Zealand to activate your residence status, we encourage you to travel as soon as possible.
If your circumstances change before arrival in New Zealand, and these have not been declared and cleared by Immigration New Zealand, complications can arise at the border or in later applications.
If Your Circumstances Change.
Not every situation is the same. However, if any change of personal circumstances happens before the resident visa is activated (by arriving in NZ for the first time or the visa is issued when the person is already in NZ), advice must be taken.
Anything that may affect the decision to issue the visa needs to be considered. This can include changes to the job offer, new health and character problems or even a replaced passport.
Consult with a licensed immigration adviser who can advise on the next steps to take.
Of course, you don't expect anything to go wrong, but if it does, all your plans can fall apart.
Please do NOT delay in completing these final steps after Approval in Principle.
