ADSL Broadband

Standard fixed line broadband, for your home

ADSL Broadband is fast, reliable, and available at most places in New Zealand. ADSL can be bundled with a home phone or used on it's own (called 'Naked'). ADSL stands for "Asymmetric Digital Subscriber Line". The 'asymmetric' part of the definition means that download speeds and upload speeds are not the same. In other words, download speeds are faster than upload speeds.

  • ADSL uses the Chorus legacy copper network (previously Telecom).
  • ADSL is ideal for basic activities, like web browsing, email and online banking.
  • ADSL is available across many parts of New Zealand.

ADSL was once the most common type of broadband found in New Zealand homes, but that is no longer true. Fibre broadband has become the most common type of broadband connection available in New Zealand.

About ADSL speeds

ADSL is slower than both VDSL and Fibre broadband. Within the Chorus copper network, there are two varieties of ADSL, these are ADSL and ADSL2+. The big difference between the two is speed. For ADSL speeds, please visit Broadband plans.

If you can't get VDSL at your location, for faster speeds, or if you won't be able to get Fibre broadband for some time, you could consider Wireless Broadband.

ADSL installation

In most cases it's very easy to install an ADSL connection. Simply follow the installation instructions we've included with your modem on your connection date, and you're done. However, in some instances, you may require a Connection and Wiring option, which will need a visit from a technician if:

  • You have more than 5 phone lines in use
  • You have a monitored home alarm
  • You use the interactive facilities on SKY Digital
  • You use a PABX phone system

Please note: Even if none of these instances apply to you there is a chance that you may be required to have Connection and Wiring done.

Broadband FAQs

What is the 111 Contact Code?

The Commerce Commission's 111 Contact Code (“111 Code”) was created to ensure that Vulnerable Consumers have reasonable access to an appropriate means of calling 111 emergency services in the event of a power failure.

Newer home phone services such as voice calling over broadband, which rely on an active working broadband service, won’t work in the event of a power failure, without an independent power source. The 111 Code requires Telecommunication Service Providers to provide Vulnerable Consumers with an alternative solution to contact 111 in an emergency.
If you are receiving One NZ household voice calling over broadband services over Fibre, HFC, VDSL, ADSL or Wireless technology and you, or someone you live with, do not have access to a traditional copper phone line, and is likely to need to contact 111 for health, safety or disability reasons and, you do not have the means to do so during a power failure, please read the information below and fill out a Vulnerable Consumers Application Form.

If you qualify, One NZ will provide you with an alternative means of contacting 111 in the event of a power failure, free of charge.

What is the difference between ADSL, VDSL, Fibre, HFC and Wireless broadband?

The difference between these broadband technologies is speed and the method of delivery.

  • ADSL stands for 'Asymmetric Digital Subscriber Line', and it uses the copper network from Chorus. ADSL is ideal for basic internet activities like web browsing, email and online banking.
  • VDSL is faster than ADSL, but it is not as fast as Fibre. VDSL lets you enjoy better HD video streaming and sharper online video chats, when compared to ADSL.
  • HFC is faster than both ADSL and VDSL. HFC is a One NZ's hybrid fibre coaxial network, that uses world-leading DOCSIS 3.1 technology to deliver high speed data.
  • Fibre Broadband is faster than ADSL and faster than VDSL. Fibre broadband delivers your data over fibre optic cables, much faster than other technologies. Fibre is now the most common type of broadband connection.
  • Wireless Broadband is delivered over our 4G mobile network or our 5G mobile network. The modem comes with a SIM card pre-installed, making it very easy to set up.

What is Naked Broadband?

Naked broadband is an internet connection without a home phone and is available with ADSL, VDSL, Fibre, HFC and Home Wireless Broadband plans.

What's the process for getting Fibre installed?

Once you’ve signed up for a fibre plan, you will then need to choose a date for our technician to come and discuss your installation with you. During this meeting, they will let you know if there’s any digging involved and confirm if you need your neighbours’ consent before the installation.

Once this is complete, our fibre broadband team will set up the fibre connection outside your house, development or apartment complex.

You then need to agree to a date for the line to be connected inside your home. You will need to be at home during this step. The installation steps may all happen in one day, or it may take more than one visit depending on what’s required.

How much data do I need?

Your data usage is decided by two factors – the number of devices in your home and the type of content that will be consumed. If you have multiple devices, you will need higher data to ensure each device has enough, especially if each device is being used to stream audio or video.

Even if you have fewer devices, but stream a lot of high definition video or music, it would be better to pick a broadband plan with higher data limits.

If you want to get a more detailed breakup of how much data you’ll need per month, check out this handy data calculator from Chorus.

Will broadband affect my monitored alarms?

Fibre broadband can be used with monitored alarms, but fibre won't work during a power outage. That means that your alarm may not working if the power fails.

Some alarm models aren't compatible with fibre broadband. Before you install fibre broadband, please check with your alarm supplier or manufacturer, whether you need to upgrade your alarm model.

Monitored alarms are, unfortunately, not compatible with our Wireless Broadband.
