What is the security and customs regime for entry into New Zealand?

The correct choice highlights an important aspect of New Zealand's security and customs regulations. All travellers entering the country are required to declare food items and outdoor equipment, regardless of their origin. This policy is in place to protect New Zealand's unique environment and agriculture from pests and diseases that can be introduced by foreign products.

Food items, including fruits, vegetables, dairy products, and meat, as well as outdoor equipment that might come into contact with soil and plants, pose a potential risk if they carry unwanted organisms. By enforcing these declaration requirements, New Zealand aims to maintain its biosecurity measures and preserve its natural ecosystems.

The other options do not accurately reflect the customs and biosecurity requirements for entering New Zealand. Only allowing residents to enter without declaration, stating that there are no restrictions on food items, or suggesting that only cash declarations are necessary do not align with the established customs protocols that emphasize the importance of declaring specific categories of items upon entry. This proactive approach helps ensure the health and safety of New Zealand's agriculture and environment.
