Measuring New Zealand’s broadband performance
This page was updated1 month ago
The Commission runs a programme to measure the broadband performance of households across Aotearoa New Zealand.
The aim of the Measuring Broadband New Zealand monitoring programme (MBNZ) is to provide consumers with independent information on broadband performance across different providers, plans and technologies, to help them choose the best broadband for their household. Shining a light on actual broadband performance will also encourage telecommunications providers to compete on performance and not just price.
Following a review of the MBNZ programme and a robust procurement process, the Commission has appointed SamKnows to continue delivering the programme for the next 3 years. SamKnows is a world leader in internet performance measurement.
View the latest resultsBecome a broadband volunteer
To make sure we get an accurate picture of how New Zealand’s broadband is performing, we need volunteers from all parts of the country, on different types of broadband technologies, plans and with various providers, to take part.
We especially want volunteers who have Fixed Wireless (4G, 5G, and also WISP based Fixed Wireless) and satellite, many of whom will be in rural locations. If you are one of these consumers, please volunteer using the sign up link below.
If you do not want to volunteer, you can still use the information from the programme to help you choose the right broadband for you.
Volunteers selected for the programme will have access to their own personal internet performance results, and to RealSpeed which gives them the ability to assess their WiFi performance – a tool, which may help diagnose problems and improve home broadband performance.
If you are selected, you will be provided with a ‘Whitebox’ (similar to a modem) to plug in at home. The Whitebox performs automated tests on your home internet performance at different times of the day. It will not record any personal information or browsing history and does not interfere with your internet service. Some of your broadband data will be used to conduct testing (see below for the approximate data usage).
If you are selected, SamKnows will contact you directly.
You will not be paid to participate in the programme, and it will not cost you anything to participate.
Data usage
The faster your broadband connection, the more data the testing will use. We have set out the likely data usage in the table below.
For volunteers on ADSL, your connection will not be fast enough to use much data, so the testing should use less than 10% of your monthly cap.
If you have a data capped plan for VDSL, Fibre or HFC (Cable), you will probably not be selected for the programme, as we do not want you to get charged for going over your data cap.
If you have a Fixed Wireless (4G or 5G modem, or WISP Fixed Wireless) connection with a data cap, you have the option of opting for the lightweight testing programme, which will test less frequently to keep the data usage down. Both the standard and lightweight testing usage is shown in the table below, so you can opt for the one you feel most comfortable with.
No matter what broadband plan, data cap or technology, the testing will not run when you are using the internet so it will not affect your broadband performance.
Typical average data usage shown is based on a NZ Standard Testing (full testing programme) unless otherwise stated.
Plan or technology | Typical average download and upload speeds (Mbps) | Typical test data usage per month (GB) |
