Detailed observation of presented data
New Zealand’s Facebook Ads benchmarks for Cost per Purchase in 2025 tell a story of sharp swings around an otherwise modest full‑year average. While the global market held steady around the low‑50s, New Zealand averaged 49.4, finishing well below where it began after a dramatic mid‑year surge and an equally steep late‑year slide. Peaks arrived late (August), troughs landed hard (November), and volatility was many times higher than the global pattern. 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.
New Zealand started 2025 elevated at 74.0 and ended at 25.7, a 65% drop across the year. The median Cost per Purchase ranged from a high of 83.5 in August to a low of 20.9 in November, averaging 49.4 across the twelve months. The path was anything but linear: a 40% pullback from January to February (74.0 → 44.5), a further slide into April (29.5), then a powerful run-up through winter to the August peak (+183% from April to August). From there, costs collapsed by 52% in September and kept falling into November before a 23% rebound to December.
Volatility was the defining feature. New Zealand’s month‑to‑month absolute change averaged 16.4 points, compared to just 1.6 globally—roughly ten times the swing. The sharpest single move was August to September (−43.6 points), with additional breaks in January to February (−29.5) and April to May (+20.8).
Seasonality played out atypically in New Zealand. Q1 opened high and eased into an April trough—a common early‑year pattern—but the market then marched higher into mid‑winter, culminating in August’s year‑high. The back half diverged clearly from global rhythms: instead of gradually firming into Q4, New Zealand’s Cost per Purchase weakened markedly through spring and early holiday weeks, bottoming in November before stabilizing in December. On a half‑year basis, H1 averaged 52.8 versus 46.0 in H2, a 13% decline; globally the decline from H1 to H2 was gentler at about 4%.
Against the global benchmark (51.7 average), New Zealand ran slightly cheaper overall (−4%), but with much wider amplitude. The market sat above global levels in January (+39%), June (+32%), July (+48%), and August (+57%), and below in most other months: February (−19%), March (−2%), April (−44%), May (−4%), September (−25%), October (−37%), November (−56%), and December (−46%). The gap was narrowest in March (rough parity) and widest in August (+57% above) and November (−56% below). While the global trend eased gradually from February’s high (54.8) to December (47.6) for a 10% year‑end decline, New Zealand traced a choppier arc—soaring into August before a late‑year reset.
As a snapshot of country‑specific ad costs, these Facebook Ads benchmarks highlight how Cost per Purchase for all industries in New Zealand in 2025 hovered slightly below the global average but moved far more dramatically month to month. Understanding Cost per Purchase trends in New Zealand—alongside the steadier global baseline—helps contextualize industry ad performance and compare local outcomes 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.

All data is sourced from over $3B in Facebook ad spend, collected across thousands of ad accounts that use Superads daily to analyze and improve their campaigns. Every data point is fully anonymized and aggregated—no individual advertiser is ever exposed.
This dataset updates frequently as new ad data flows in. It will only get bigger and better.
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.
