For best results:

  • Close all apps.
  • If you have a wireless router, make sure you're connected using an ethernet cable.
  • Only have one computer, tablet or mobile connected to the internet when doing a speed test.
  • Choose your nearest location, eg, Auckland, Wellington or Christchurch.
  • Repeat the test a couple of times to get an average speed.

Test results

  • FibreMAX: Up to 900Mbps for downloading and 400Mbps for uploading.*
  • Fibre 200: Up to 200Mbps for downloading and 20Mbps for uploading.
  • Fibre 100: Up to 100Mbps for downloading and 20Mbps for uploading.
  • FibreBASIC: Up to 30Mbps or 50Mbps for downloading and 10Mbps for uploading.**

* Ultra Fast FibreMAX is next generation broadband delivered at blistering speeds, over the fastest residential Fibre service in NZ (using gigabit technology). In optimal conditions - such as those we recommend below^, most customers should see between 700Mbps-900Mbps on a speed test, although some connections may achieve even better than this. In order to get the best performance out of your Ultra Fast FibreMAX service, you might need to change the way you're connecting to the internet, and most importantly you will need to have high specification hardware in your home. Spark terms and charges will apply.

^ To get the best possible performance from Ultra Fast FibreMAX broadband, we recommend using:

A high-spec modem that is capable of supporting these types of speeds, such as the Huawei HG659b from Spark

  • A high-spec laptop or PC, for example Intel i5-3550 3.3Ghz CPU, with 8GB RAM running Windows 10 Home 64 bit operating system and cabled directly into your modem with an Ethernet cable, and ensure all your laptop or PC's drivers are up to date, and nothing else is running on the internet connection at the same time, and
  • The latest version of your browser, for example Chrome 54.0.2840.87, Mozilla Firefox 49.0.2.
  • And always test with a local speed test server (for Spark customers this is www.spark.co.nz/speedtest).

** FibreBASIC has a different speed depending on your Local Fibre Company. Addresses in Whangarei, Hamilton, Whanganui, New Plymouth, Tokoroa, Hawera, Cambridge, Te Awamutu, Tauranga and Christchurch will have a Fibre service with the ability to deliver speeds up to 30mbps downstream and 10mbps upstream. The rest of New Zealand will have a service able to deliver up to 50Mbps downstream and 10Mbps upstream.

What affects broadband speed

  • Actual speeds differ due to networks, and the computer or modem you're using. Your home wiring can also impact internet speed.
  • Speeds vary based on how many people are on the network at the same time, both in your house and in general. Your distance from your nearest internet server would also impact the internet speed.
  • Connecting straight to your modem using ethernet wiring provides the fastest connection speed.

What affects WiFi speed

  • The age of your modem. Older modems could reduce your WiFi speed. That said, WiFi is not always improved by the quality or the cost of your modem.
  • Your internet connection speed. WiFi can't run faster than the speed your modem gets data from the internet.
  • The number of devices you have connected. If you've got an ADSL connection, your WiFi speed can slow down when several devices are online at the same time.

Tips for fast broadband

  • Use a high-spec modem and a high-spec laptop or computer.
  • Keep your browser up to date.
  • Make sure you're using up-to-date antivirus software. Viruses can slow your internet down.
  • Check your data usage. You may go back to dial-up speed for the rest of your billing month if you reach your monthly data allowance.
  • If the broadband seems slow, reset the modem by turning it off for a couple of minutes, then turning it on again.
