Cost Per App Install in New Zealand

January 2025 - January 2026

Insights

Detailed observation of presented data

Introduction

New Zealand’s all-industry Facebook Ads cost per app install (CPI) told a year of sharp swings: a costly start, a dramatic Q2 reset, then a measured rebound into year-end. Compared to the global benchmark, New Zealand averaged higher CPI overall but with far bigger month-to-month moves. January and February sat well above market, April plunged to the year’s floor, and December closed with a notable uptick even as the global benchmark eased.

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 began 2025 at $44.65 per install in January and finished at $15.16 in December, a 66% decline from start to finish. The year’s high was indeed January ($44.65), while April marked the low at just $2.53 — a 94% drop from the January peak. Across the year, New Zealand’s CPI averaged about $16.4.

The most dramatic movement came early: February slipped 22% from January, and by April CPI had fallen 93% from February. From that trough, costs rebuilt steadily: April to August climbed more than sixfold (to $17.73), then moderated into October ($9.80) before rebounding in November–December, ending the year at $15.16. Volatility was a defining feature: the average month-to-month swing was roughly $7.7, about 47% of the annual mean.

Globally, CPI averaged about $13.4, ranging from $7.07 (January) to $23.76 (June). Month-to-month movement was milder, averaging $4.6 — materially calmer than New Zealand’s cadence.

Seasonal and monthly dynamics

New Zealand’s pattern ran counter to typical mid-year pressure seen in app install markets. Q1 was elevated (average $29.4) on the back of steep January–February costs. Q2 marked the trough (average $10.6), bottoming in April. Q3 stabilized at mid-teens ($13.5) with a slight August crest, while Q4 held close to Q3 levels ($12.1) with a year-end lift in December.

The global rhythm, by contrast, rose into Q2 (June peak at $23.76), cooled through Q3–Q4, and finished the year at $9.32 — well below its October local high. In short: global CPI built into mid-year and eased into the holidays; New Zealand spiked early, reset in Q2, and rebuilt into year-end.

Country vs. Global

On average, New Zealand CPI was about 23% above the global benchmark ($16.4 vs. $13.4). The gap, however, swung widely month to month. New Zealand ran more than 6x the global level in January and about 3x in February. It crossed below market in March (−4%) and plunged far below in April (−81%). Through mid-year, New Zealand oscillated around parity: below in May–June, modestly above in July–August, below again in September–November, then back above in December (+63%).

Volatility stood out most: New Zealand’s month-to-month change ($7.7) was about 68% larger than the global benchmark ($4.6). The range told the same story — a 17.7x high-to-low ratio in New Zealand versus 3.4x globally.

Closing

These Facebook Ads benchmarks highlight how cost per app install for all industries in New Zealand ran higher and more volatile than the global average, with an early surge, an April reset, and a late-year rebuild. Understanding country-specific ad costs and CPI dynamics — alongside broader CPC trends, CPM analysis, and CTR performance — helps situate New Zealand’s all-industry app install costs within global patterns for 2025.

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.

Potential Advertising Impact

Late November–December Black Friday/Cyber Monday could drive ad costs significantly. Regional anniversary holidays may cause local inventory shifts.

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.
