"Most New Zealanders won't be affected by these risks, but you should still be cautious when traveling to these countries."The advisory was originally issued on November 29, 2024, and remains current as of March 19, 2025. This advisory is a Level 2 as part of a four-tiered system that mirrors the U.S. Level 1: Exercise normal safety and security precautions; Level 2: Exercise increased caution; Level 3: Avoid nonessential travel; Level 4: Do not travel."There are more significant safety or security concerns than you would usually find in New Zealand, particularly because of terrorism and civil unrest."There is a higher incidence of violent crime and firearm possession than in New Zealand," the advisory continues.It also alludes to active shooter incidents, crime (petty acts including theft in urban and tourist areas), natural disasters and severe weather, and entry requirements related to immigration laws.The country's SAFETRAVEL website also encourages New Zealanders to review an active shooter response pamphlet issued by the US Cybersecurity & Infrastructure Security Agency.Newsweek reached out to the New Zealand government and U.S. embassies for comment.Canada and Australia encourage their citizens traveling to the U.S. to take normal security precautions.The Canadian government warns of criminal incidents often involving drugs near the U.S.-Mexico border, specifically mentioning Arizona, California, New Mexico and Texas.Both countries also allude to petty and violent crime, gun violence, home break-ins for Canadians who live in the U.S. on holiday or during winter months, fraud, terrorism and demonstrations or protests potentially becoming violent.As of March 11, 2025, the U.S. Department of State issued "Level 4: Do Not Travel" advisories for several countries including Afghanistan, Belarus, North Korea, Russia and Ukraine.What Happens NextMost countries consistently update their advisories to best provide tips and guidance to citizens traveling abroad, including those already abroad but stranded.
