COMvergence releases Final 2025 New Zealand Billings and Market Share Report
Global media and advertising research firm COMvergence has released its annual New Zealand Billings and Market Share report.
The report presents final 2025 media agency and group billings figures, including digital media investments.
Olivier Gauthier, COMvergence founder and CEO, says: “This report provides the most comprehensive and transparent view of the global media agency landscape for 2025.
“As the industry continues to consolidate, it is more important than ever to have clear, reliable benchmarks – and to distinguish between what has happened and what is projected.”
Group ranking: Omnicom Media extends its lead
At the group level, Omnicom Media Group retains the top position with a 38.1% industry market share and USD $565M in billings, with a market leading increase versus 2024 (6.6%).
The acquisition of IPG by Omnicom was approved in late 2025. Combining the media billings figures of Mediabrands and OMG into the new Omnicom Media group would bring the total to $673M, placing the new group in a potential first position.
Publicis Media follows with USD $239M in 2025 billings (+2.0% vs. 2024). WPP Media ranks third with USD $156M (-6.1% vs. 2024).

Key takeaways
The billings managed by media agency networks owned by the Big 6 HoldCos. plus major independent media agencies reached USD $1.2B in 2025, experiencing an overall growth of +1.8% vs. 2024.
COMvergence estimates that digital media accounted for 44% of New Zealand media billings in 2025, totaling USD $535M (+13% vs. 2024) across the Big 6 groups and major independent agencies.
Digital shares are calculated based on total billings from the media agencies and groups covered in its New Zealand Billings and Market Share report, and therefore excludes advertisers’ in-house digital spend as well as billings handled by digital and performance pure players.
The FY 2025 New Zealand New Business Barometer (released March 2026) recorded a total reviewed media spend of USD $91M, representing 8% of total billings controlled by the Big 6 plus independent agencies.
