Detailed observation of presented data
New Zealand’s cost per purchase (CPP) told a year of two halves: a mid-year surge that briefly sat well above the global benchmark, followed by a sharp Q4 reset that dropped far below market levels. Across all industries, CPP in New Zealand averaged 48.9 for the year, slightly below the 51.4 global average, but with far greater month-to-month turbulence. August was the costliest point at 83.5, while November marked the low at 17.8 — a 79% swing in just three months. This analysis is based on $3B worth of advertising data from our dataset, which provides strong directional benchmarks. This analysis explores ad performance trends for all industries in New Zealand compared to the global benchmark.
The year opened elevated at 74.0 in January, softened through April (29.5), then accelerated into a mid-year peak: June (66.3), July (72.9), and August (83.5). From there, CPP retraced quickly: September fell to 39.9, October to 33.1, and November bottomed at 17.8 before a modest December rebound to 22.7. Overall, New Zealand’s CPP averaged 48.9, with a median of 47.4, ranging from 17.8 to 83.5.
Volatility was the defining characteristic. The average month-to-month absolute change was 16.7 points in New Zealand, versus just 1.8 globally — nearly 9x more turbulent. The largest single move was August to September, a 52% drop (−43.6 points). January to December, CPP declined 69% in New Zealand, compared with a 15% decline globally (53.3 to 45.1).
Seasonality appeared inverted relative to typical Q4 inflation often observed in CPC trends and CPM analysis. Q1 in New Zealand averaged 56.7, Q2 dipped to 48.7, Q3 lifted strongly to 65.4, and Q4 reset to 24.6. The Q3 run-up culminated in the August high, then unwound swiftly in September and October. Performance typically softens through Q4 as competition rises, yet New Zealand’s CPP moved from a mid-year premium to a pronounced late-year discount, with the November trough marking the low point for country-specific ad costs.
Relative to Facebook Ads benchmarks worldwide, New Zealand oscillated between above-market and deep discounts:
Globally, CPP was steadier: a tight range from 45.1 to 54.8 and a gentle downtrend across the year. New Zealand’s arc was choppier, with sharper peaks and deeper troughs.
In sum, Facebook Ads cost-per-purchase benchmarks for all industries in New Zealand show a mid-year spike and a pronounced late-year reset, averaging slightly below global costs but with far higher volatility. Understanding CPP trends for all industries in New Zealand helps marketers gauge country-specific ad performance and compare it to global patterns.
Insights & analysis of Facebook advertising costs
Facebook advertising costs vary based on many factors including industry, target audience, ad placement, and campaign objectives. Different industries see varying ad costs due to market competition, user demographics, and conversion value. For campaigns targeting New Zealand, advertisers should consider local market factors and user behavior. Different campaign objectives lead to varying costs based on how Facebook optimizes for your specific goals. The data shown represents median values across multiple campaigns, and individual results may vary based on ad quality, audience targeting, and campaign optimization.
We use the median CTR because the underlying distribution of click-through rates is highly skewed, with a small share of campaigns achieving extremely high CTRs. These outliers can inflate a simple average, making it less representative of what most advertisers actually experience. By using the median—which sits at the midpoint of all campaigns—we provide a more rigorous and realistic benchmark that reflects the true underlying data model and helps you set attainable performance expectations.
Note: This data represents industry median values and benchmarks. Your actual costs may vary based on specific targeting, ad creative quality, and campaign optimization.

Late November–early December (Black Friday/Cyber Monday), Christmas season (Boxing Day sales), Mid‑year promotions (Matariki in June), Back-to-school (late January/early February)
CPM and CPC might rise around Waitangi Day and ANZAC Day as public events increase media consumption. Matariki is new public holiday with growing awareness—advertising may see elevated competition. Late November–December Black Friday/Cyber Monday could drive ad costs significantly. Regional anniversary holidays may cause local inventory shifts.
It depends on your product price and margins. Most brands aim for $10 to $50. For higher-ticket products, a higher CPA may be acceptable as long as you're maintaining a strong return on ad spend.
Higher-priced products typically have a higher CPA because people take longer to convert. That's not necessarily a problem if your margin can support it. You should measure CPA in context with AOV and LTV.
Your AOV may be increasing, which helps maintain ROAS even if CPA rises. You could also be facing higher CPMs, lower conversion rates, or creative fatigue.
Manual bidding can help if you're struggling to stay within target CPA. It's best used by experienced advertisers who can monitor performance and adjust regularly. It gives more control, but also requires more effort.
Increase budget gradually, rotate creative often, and avoid overlapping audiences. Scaling too quickly can lead to audience saturation and rising CPAs.
