Can I still use my old passport while applying for a new New Zealand passport?

1. As long as the old passport is valid, it is valid and can be used. However, it should be noted that many countries require that the passport of foreigners entering the country be valid for more than 6 months. Therefore, if the passport is valid for less than 6 months, it is recommended not to take the passport for international travel. If the new passport has been obtained, the old passport is still valid and has a valid visa on it, then according to international practice, the old and new passports can be used together and the visa on the old passport can be used to enter the country.

2. Passport is a legal document issued by a country to prove the nationality and identity of its citizens when they enter or leave its territory and travel or stay abroad. The word passport means port pass in English. In other words, a passport is a pass for citizens to travel through international ports in various countries. Therefore, some countries in the world usually issue passes instead of passports.

In any of the following circumstances, the passport holder may apply for renewal or replacement of the passport according to the regulations:

(1) The validity period of the passport is about to expire;

(2) The passport visa page is about to be used up;

(3) The passport is damaged and cannot be used;

(4) the passport is lost or stolen;

(5) Other circumstances that justify the need to renew or reissue passports.

a visa is the endorsement and seal of a country's sovereign organs on passports or other travel documents held by its own or foreign citizens to show the procedures for allowing them to enter or leave its own territory or pass through it. It can also be said that it is an endorsement certificate issued to them. Generally speaking, a visa is a document issued by a country's entry-exit management agency (such as the Immigration Bureau or its embassies and consulates abroad) to express approval for foreign citizens to enter the country.
