Reports based on testing indicate that ad-delivery systems increasingly influence which voters see political messages online. RNZ reports that National and ACT political ads tend to reach more men, while Green Party ads reach a higher share of women.
The Conversation explains the broader context: although parties design election ads, automated systems run by technology companies can determine audiences through targeting and ranking algorithms. This can affect who sees ads even when parties set their own campaign goals. The outlets emphasize that such results raise questions about transparency and accountability in online political advertising.
While the specific findings focus on differences by audience demographics, the overall issue highlighted across sources is the growing role of algorithmic delivery in election communications. The Conversation calls for urgent transparency so voters can better understand how ad exposure is determined. The reporting cited frames these disparities as something that regulators and the public may need to assess more closely.
