MERCURY MOBILE
If fibre is unavailable in your area, or you are ready to update your copper connection, our reliable wireless broadband is an excellent alternative.
You can choose one of our wonderful offers when you bring your electricity and broadband together with Mercury.
WHAT IS WIRELESS BROADBAND?
Wireless broadband uses the 4G mobile network instead of underground copper or fibre cables, making it a great alternative if fibre isn’t available at your address. It runs on the same technology your mobile phone uses to connect to the internet.
With 4G coverage across most of New Zealand, Mercury’s wireless broadband is quick to set up and includes a router with every plan—so you can plug in and get online fast.
4G wireless broadband is generally faster than ADSL copper connections, though not as fast as fibre. Actual speeds can vary depending on your home’s location, router placement, device age, number of connected devices, and overall network traffic.

*Prices include GST. Prices may change during the term. T&Cs and early termination fees apply. Router included, P&H $14.95. Broadband plans and pricing are dependent on location/availability.
**Speeds shown are the Spark national average speeds for Wireless Broadband at busy times (source: MBNZ Report 25, October 2025). You may experience a higher or lower speed than this. Broadband speeds explained. 1,000GB and 300GB data plans run at maximum speed to data threshold, then are throttled to 5Mbps until the plan renews. 120GB plan is capped and once data cap has been reached, service will stop until the plan renews, unless data packs are purchased to continue service at maximum speed.
If you have a capped wireless broadband plan and use up your monthly base plan data, to keep you online you will have one 10GB extra data pack automatically added and charged to your account. If you use all your base plan data as well as this additional Auto Allowance, your broadband service will stop (until your monthly plan renews) unless you top up manually with an Add-On pack. We recommend purchasing Add-On pack when needed as they provide you with great value for money. They need to be manually purchased by you and do not automatically renew each month. Check out the packs available below. It’s easy to add or remove a pack with the Mercury app. You can download our app from the app store. From there, simply head to the Broadband section within the app to manage your Wireless Broadband plan.
Auto-Allowance Data Packs:
Data Pack - 10GB $10
One available per 30 days
Add-On Data Packs:
Up to 4 available per 30 days

Any unused wireless broadband base plan data doesn’t carry over to the next billing period and will expire at the end of the month.
Data from any 10GB data pack—whether purchased manually or added automatically—lasts for 30 days, and any remaining data expires at the end of that period.
When your plan renews, your oldest data is always used first.
