In 2013, RNZ National had a 10.3 per cent market share, the highest nationwide and up from 9.1 per cent in 2009. Market share peaked at 11.1 per cent in 2011, probably due to the station's coverage of the Christchurch earthquake. In 2014 493,000 people listened to RNZ National over the course of a week – the second-largest cumulative audience. A 2021 survey estimated 609,800 listeners (13.5% of the 10+ population), Morning Report being the most popular, with 434,000 listeners.
