Detailed observation of presented data
New Zealand’s cost-per-purchase profile is a study in momentum: higher on average than the global benchmark, but punctuated by sharp spikes and deep troughs. 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.
Across the 13-month window from June 2025 to June 2026, New Zealand’s median cost-per-purchase averaged about $61.8, starting at $65.26 (Jun‑2025) and finishing near $64.04 (Jun‑2026) — essentially flat over the period but far from steady month-to-month. The high point was $79.59 in August 2025 and the low was $37.27 in November 2025. That peak-to-trough swing (~$42.3) reflects unusually large moves for a single market.
By contrast the global baseline averaged roughly $48.2. On average New Zealand ran about 28% above the global cost-per-purchase, but the gap varied wildly: NZ was roughly 25% below global in September 2025 (NZ $39.53 vs global $53.03) and as much as 151% above global in June 2026 (NZ $64.04 vs global $25.50). Month-to-month momentum was extreme — August to September 2025 saw a dramatic drop of about 50% (from $79.59 to $39.53), followed by a rebound to $66.30 in October (+67.6% vs September).
Volatility measured as average absolute monthly change was about $13.3 in New Zealand versus about $4.2 for the global baseline — roughly three times more volatile, showing sharper swings than the broader market.
The rhythm shows clusters of instability rather than a smooth seasonal curve. Late Q3 (August) produced a costly spike that reversed sharply into early Q4; November marked the year’s trough; Q4 into early Q1 saw a staged recovery, and spring 2026 (Feb–May) held elevated levels with smaller oscillations before a modest dip into June. The global baseline, while not identical in timing, displayed a dramatic end-period decline driven by a much lower June 2026 median ($25.50), pulling the global average down even as New Zealand remained comparatively elevated.
These movements read differently than CPC trends or CPM analysis might imply: cost-per-purchase here is reacting in concentrated bursts, creating a stop-start monthly cadence rather than a steady seasonal slope.
Relative to the baseline, New Zealand’s cost-per-purchase was generally above market but intermittently below average. Overall NZ ran about +28% vs global, with month-level divergence from roughly −25% to +151%. The market was more volatile and episodic — larger spikes and deeper corrections — while the global benchmark was steadier across most months until the late-period drop. In plain terms: New Zealand exhibited higher median cost-per-purchase and materially greater month-to-month swing than the global view.

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.
