New Zealand's entry and exit are very strict. When you go through the customs in New Zealand, you are not allowed to carry jewelry and ornaments made of turtles or tortoise shells, medicinal musk, rhinoceros horn, tiger products, leather products, whales and other marine biological skeleton products.

New Zealand is an agricultural country, and many foreign things will have an impact on its environment. The pipe products it carried were not truthfully declared. Once found, the lighter may be fined, and the heavier may be revoked or given criminal sanctions.
