What is a Radio Survey?

In order to stay ahead of trends and plan the smartest campaigns, access to the latest facts and figures is crucial. GfK’s commercial radio surveys produce invaluable data on who is listening, to what and where.

Key Definitions

Station Share: The percentage of all radio listening that is done to a station over a week; it takes into account the number of people listening and how long they listen.

Cumulative Audience: The theoretical maximum audience that a station can reach. Cume is the total number of different listeners who tune in to a radio station for at least 8 minutes within a daypart during the week.

Average Audience: The average number of listeners you will reach in any given quarter hour of the station and time zone selected.

Rolling Surveys

GfK conducts rolling surveys to get an accurate depiction of commercial radio listenership in New Zealand (both terrestrial & digital). Each survey adds a new wave of sample and drops off the oldest.

Multi-mode Methodology

A combination of paper diaries, eDairy and CATI placements is utilised to gather survey data. The sample is made up of Kiwis across varying demographics, locations and ethnicities.
