Total monthly data use by residential and business broadband connections in New Zealand

Residential and business connections include digital subscriber line, cellular (does not include mobile phone connections), wireless, cable, satellite, and fibre optic connections.
For 2014, this figure is likely to be an undercount due to a number of businesses who were unable to provide an answer for this question.

The Internet Service Provider (ISP) Survey is a survey sent to all New Zealand-based Internet service providers. The target population for the ISP Survey in 2018 was 92 businesses.

Businesses that provided other Internet services, such as web and domain hosting, but that did not provide ISP services, were excluded from the population. This is because the primary activity of an ISP is providing a connection to the Internet. Web-hosting units do not meet this condition, but rather, provide Internet-based services. Businesses that provide only occasional or unmetered access (including Internet cafes, kiosks, libraries, and universities) are also excluded. The activity of this group is covered by the ISP each business subscribes to, and so do not need to be surveyed separately.

The main objective of the ISP Survey is to provide the government with information on the total number and nature of the subscribers that use New Zealand based ISPs to connect either permanently or regularly to the internet.

The Internet service provider survey used to be a postal survey of all businesses that meet the population selection criteria. In 2018 Stats NZ tried a new online mode for the survey.
