Benchmark observations based on the selected data
The main story: cost-per-purchase in New Zealand ran consistently above the global benchmark across most of the year but with sharp month-to-month swings — an early summer peak, two steep troughs in September and November 2025, then a steady rebound into a late‑Q2 high. 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’s median cost per purchase averaged about $62.8 over the 12‑month window (July 2025–June 2026), versus a global median of roughly $49.9 — about 26% higher on average. The local series peaked at $79.15 in August 2025 and troughed at $37.27 in November 2025, a peak that was roughly 112% higher than the trough in absolute terms. Monthly movement was lively: the average absolute monthly change was about $14 (≈22% of the NZ average), driven by a few large moves (a ~$39 drop from August→September and ~$29 from October→November) and several rebounds into Q1–Q2 2026.
Across the year New Zealand spent 10 of 12 months above the global level. The gaps varied: July and August 2025 were substantially higher (+43% and +52% vs. global), September dipped ~25% below the global median, and by June 2026 New Zealand was ~83% above the global rate as the baseline softened.
The rhythm shows early volatility around the Southern Hemisphere spring/summer transition and a mid‑season soft patch. Two clear trough months — September and November 2025 — interrupt a pattern of high midsummer costs. From December through March the series staged a measured recovery (December ~parity with global, January–March progressively higher), followed by strong Q2 momentum that culminated in June 2026’s high.
This pattern reads like alternating compression and release: a brief collapse after the August spike, recovery into the new year, then renewed build into late‑Q2. Compared with typical seasonal narratives (Q4 competitive pressure and Q1 rebounds), New Zealand’s timeline shows more abrupt swings rather than smooth seasonal slopes.
Relative to the global baseline, New Zealand was consistently above average for most of the period and markedly more volatile. The baseline’s average absolute monthly swing was about $3.1 (≈6% of its mean), compared with New Zealand’s ~ $14 (≈22%), meaning New Zealand’s month‑to‑month movement was roughly 4.5× larger. At its narrowest gap (December 2025) New Zealand was essentially at parity with the global median; at its widest (June 2026) it was ~83% above baseline. Overall this paints a picture of higher cost-per-purchase levels and stronger month-to-month fluctuations for All industries in New Zealand versus the global benchmark.

Facebook advertising cost benchmarks
Facebook advertising costs vary by industry, target audience, ad placement, and campaign objective. Ad costs vary across industries because of competition, audience demographics, and conversion value. For campaigns targeting New Zealand, advertisers should consider local market factors and user behavior. Campaign objectives affect costs because Facebook optimizes delivery for different goals. The data shows median values across multiple campaigns. Results can vary with ad quality, audience targeting, and campaign optimization.
A small share of campaigns has extremely high CPP values. Those outliers can inflate an average. The median is the midpoint across campaigns, so it better represents a typical result.
The data shows industry median benchmarks. Costs can vary with targeting, creative quality, and campaign optimization.

The dataset includes over $3B in Facebook ad spend from thousands of ad accounts that use Superads to analyze and improve campaigns. Every data point is anonymized and aggregated. It does not expose an individual advertiser.
The dataset updates as new ad data is available.
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 may rise around Waitangi Day and ANZAC Day as public events increase media consumption. Matariki is a new public holiday with growing awareness, and advertising may face more competition. Black Friday/Cyber Monday in late November–December may raise ad costs. Regional anniversary holidays may shift local inventory.
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. A higher CPA can work when the margin supports it. Measure CPA 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 advertisers stay within a target CPA. It suits experienced advertisers who can monitor performance and adjust regularly. It provides more control and requires more effort.
Increase budget gradually, rotate creative often, and avoid overlapping audiences. Scaling too quickly can lead to audience saturation and rising CPAs.
