CTV's Measurement Blind Spot: Why NZ Marketers Must Re-evaluate Audience Accuracy
Recent findings reveal significant inaccuracies in Connected TV (CTV) audience matching, with IP-to-postal data proving highly unreliable. This challenges the industry's focus on scale over genuine audience truth, urging marketers to scrutinize their CTV measurement strategies.
What Happened
- •Truthset research indicates only 13% accuracy for IP-to-postal matches in Connected TV (CTV) advertising.
- •The industry has prioritised match rates and scale, inadvertently overlooking the precision of audience targeting.
- •This exposes a fundamental flaw in how CTV campaigns are currently measured and optimised.
- •The focus on volume metrics has overshadowed the critical need for verifiable audience truth.
- •The article, published on 23 March 2026, calls for a shift in CTV measurement paradigms.
Why It Matters for NZ Marketers
- •NZ marketers investing in CTV may be reaching a significantly different audience than intended, leading to wasted ad spend.
- •Reliance on inaccurate data could skew campaign performance analysis and attribution models for local brands.
- •Smaller NZ markets mean precise targeting is even more crucial; broad, inaccurate matches are less effective.
- •This issue impacts budget allocation across media channels, potentially diverting funds from more effective platforms.
- •It necessitates a deeper dive into data providers and measurement partners used by NZ agencies and advertisers.
Strategic Implications
- •Demand greater transparency and accuracy from CTV platforms and data partners regarding audience matching methodologies.
- •Prioritise quality over quantity in audience data, focusing on verified first-party data where possible.
- •Diversify measurement approaches beyond simple match rates, incorporating incrementality and business outcome metrics.
- •Educate internal teams and agency partners on the limitations of current CTV targeting and measurement.
- •Allocate resources to test and validate audience segments across different CTV providers to identify reliable partners.
Future Trend Signals
- •Increased scrutiny and demand for independent third-party verification of CTV audience data accuracy.
- •Development of more sophisticated, privacy-compliant measurement solutions beyond IP-based matching.
- •A shift towards outcome-based measurement and away from proxy metrics like match rates in CTV.
- •Greater emphasis on direct publisher relationships and first-party data integration for audience targeting.
