Cost Per App Install in New Zealand

November 2024 - November 2025

Insights

Detailed observation of presented data

Introduction

New Zealand’s cost per app install (CPI) told a dramatic story over the past 12 months: sharp early-year inflation, a steep mid-year reset, and a late-summer flare-up before settling back near where it started. Despite the turbulence, New Zealand’s all-industry CPI ultimately tracked almost exactly in line with the global benchmark on average. What stood out was not the level, but the volatility — big swings month to month and unusually large gaps versus the world in both directions.

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 story in the data

  • New Zealand’s CPI opened at 11.20 in November 2024 and closed at 9.17 in October 2025, an 18% decline end to end.
  • The annual average was 15.86, essentially at parity with the 15.81 global average (+0.3%).
  • Highs and lows were extreme: a January peak of 44.65 (the yearly high) contrasted with an April trough of 2.53 (the yearly low). The range spanned 42 points, roughly double the global range for the same period.
  • Key movements: CPI surged from December (21.70) into January (44.65) and February (35.06), then collapsed by March (8.57) and bottomed in April (2.53). A mid-year rebuild brought a sharp August jump (26.78) before easing in September (10.70) and October (9.17).
  • Volatility averaged 10.68 points month to month in New Zealand, well above the global benchmark’s 6.54, underscoring more pronounced local swings.

Seasonal and monthly dynamics

Seasonally, New Zealand diverged from a classic holiday-to-Q1 pattern. December was elevated at 21.70, but the real inflation came in January and February, where CPI averaged nearly 40 — a brief but intense spike. The second quarter flipped the script: April through June averaged just 4.71, the softest stretch of the year. A late-summer (August) resurgence to 26.78 created a secondary peak, followed by a return to sub-11 levels in September and October. In short: a front-loaded surge, a deep Q2 trough, and a one-month late-summer rebound.

Country vs. Global

Across the year, New Zealand oscillated around the global benchmark rather than shadowing it:

  • Above-market months: December (+72% vs. global), January (about 6.2x the global level), February (+172%), and August (+35%).
  • Below-market months: November (−36%), March (−7%), April (−83%), May (−53%), June (−79%), July (−32%), September (−53%), and October (−56%).

Gaps were widest in January (New Zealand far above) and June (far below). The narrowest gap came in March, when New Zealand trailed global CPI by just 7%. While the global trend rose from 7.22 in January to roughly 20–23 through late Q3 and early Q4, New Zealand was choppier — surging early, dipping hard in Q2, then briefly spiking in August.

Closing

Overall, Facebook Ads benchmarks for cost per app install show that all industries in New Zealand experienced CPI levels near the global average but with significantly higher volatility. Understanding country-specific ad costs and industry ad performance helps frame CPI trends in New Zealand against global patterns and clarifies how this market’s CPI dynamics diverged across the year.

Understanding the Data

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.

Why we use median instead of average

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.

Key Factors Affecting Facebook Ad Costs

  • Competition within your selected industry and audience demographics
  • Ad quality and relevance score – higher quality ads can lower costs
  • Campaign objective and bid strategy
  • Timing and seasonality – costs often increase during holiday periods
  • Ad placement (News Feed, Instagram, Audience Network, etc.)

Note: This data represents industry median values and benchmarks. Your actual costs may vary based on specific targeting, ad creative quality, and campaign optimization.

What's a good CPI for iOS vs Android in 2025?

iOS CPIs often range from $2 to $5 or more. Android is usually cheaper, between $1 and $3. Your CPI will depend on geo, creative, and optimization goal.

Why is my app install cost higher in some countries?

Some regions like the US, UK, and Canada have higher competition and stricter privacy regulations, which drive up costs. Countries with lower purchasing power typically have cheaper CPIs.

What creatives drive the lowest CPI on Facebook?

Short videos showing app benefits, UGC-style content, and localized messaging tend to perform best. Clear CTAs and fast-paced visuals help lower your CPI.

Should I optimize for installs or in-app actions?

Optimizing for installs gets volume, but optimizing for actions like signups or purchases brings higher quality users. It depends on your goals and how much post-install behavior matters.

How do I lower CPI without tanking app retention or quality?

Align your creative with the app experience, avoid misleading ads, and exclude users who already installed. You can also test lookalike audiences based on high-quality users, not just all installers.
