Cafes, libraries, shopping centres and airports across New Zealand often offer free internet. It is handy when you want to check emails, look at photos of the grandchildren or read the news while out and about. But many people ask the same question: is public Wi-Fi safe?

What Makes Public Wi-Fi Risky?

The honest answer is that public Wi-Fi can be risky, but it is not something to fear. Most networks are shared by many strangers, and some have little or no protection. This means a determined scammer may be able to see what you send over the connection or set up a fake network with a name that looks genuine, such as a cafe name with a small spelling change. Knowing this is half the battle.

Tasks to Avoid on Public Wi-Fi

As a general rule, keep sensitive activities for your home internet or your mobile data. Online banking, paying bills, shopping with your credit card and logging in to important accounts are best done away from public Wi-Fi. Reading the news, checking the weather or looking up a bus timetable carries far less risk.

Simple Ways to Stay Safer

If you do use public Wi-Fi, a few habits help. Always confirm the exact network name with staff before connecting. Choose websites that start with https, which means the connection is encrypted. Turn off automatic connection so your phone or tablet does not join unknown networks on its own. Keep your device updated, as updates fix security problems. A virtual private network, often called a VPN, adds another layer of protection by scrambling your data, and many reputable providers offer easy apps for seniors.

It also pays to log out of accounts when you finish and to forget the network afterwards in your settings. Be wary of any Wi-Fi page asking for personal details, such as your birth date or bank information, as genuine free networks rarely need these.

So, is public Wi-Fi safe?

It can be fine for light browsing, but it is not the place for banking or shopping. When in doubt, switch to your mobile data, which is generally more secure than a shared network. A little caution lets you enjoy the convenience without the worry. If something feels off, such as an unexpected pop-up or a request for a password, disconnect away and ask a trusted family member or friend for advice.
