* Defining "largest": Do we mean the highest attendance, the biggest stage production, the most revenue generated, or something else?
* Data availability: Not all concert attendance figures are publicly available.
* Historical record: There might be older concerts for which records are incomplete or missing.
However, some of the contenders for the title of largest concert in New Zealand history include:
* Bruce Springsteen & The E Street Band (2014): This concert drew a crowd of 70,000 at Western Springs Stadium in Auckland, making it one of the largest single-night concerts ever held in the country.
* Rod Stewart (2014): Another massive concert at Western Springs, this time attracting 50,000 fans.
* Coldplay (2017): The British band held two concerts at Auckland's Eden Park, drawing a combined total of approximately 100,000 people.
* U2 (2010): This concert at Auckland's Eden Park attracted a crowd of 50,000.
It's important to note that these are just some of the concerts with high attendance figures. Other concerts may have had larger audiences but are not widely documented.
Ultimately, the title of "largest concert in New Zealand history" is subjective and depends on how you define "largest".
