365 Day Prepaid Mobile Plans NZ
If you are looking to slash your mobile bill, switching to a long-term commitment is the single most effective move you can make. In New Zealand, 365 day prepaid mobile plans have become the "secret weapon" for budget-conscious users who want to avoid the high costs of prepay recharges and the hassle of credit checks.
By paying for a full year upfront, you can often unlock rates that are 30% to 50% cheaper than standard monthly equivalents. This guide will help you navigate the landscape of annual plans and choose the one that fits your lifestyle.
Why Choose a 365 Day Prepaid Mobile Plan?
The math is simple: convenience plus commitment equals savings. Here is why Kiwis are ditching the 28-day cycle:
-
Unbeatable Effective Monthly Cost: While you pay a larger sum upfront, the "per month" breakdown is significantly lower. For example, a $160 annual plan works out to just $13.33 per month - a price point almost non-existent in the standard monthly market.
-
Set and Forget: You only have to think about your mobile bill once a year. No more worrying about "low balance" notifications or auto-payments failing at the worst possible time.
-
Avoid Price Hikes: Paying for 365 days usually locks in your rate for the entire year, protecting you from mid-year price adjustments that often hit monthly subscribers.
Which Buyer Profile Are You? 👤
Choosing the right plan starts with understanding your usage. Here are the common types of annual plan buyers in NZ:
The "Light & Local" User 📶
Typically uses their phone for texts, calls, and occasional browsing while away from home Wi-Fi.
-
Target Plan: 18GB - 30GB per year.
-
Top Choice: Kogan Mobile Small (365 Days).
The "Daily Scroller" 📱
Uses social media, maps, and music streaming daily. Needs a reliable data cushion every month.
-
Target Plan: 40GB - 80GB per year.
-
Top Choice: Kogan Mobile Medium or 2degrees Annual Prepay options.
The "Power User" 🔥
Streams video on the go and rarely uses public Wi-Fi. Needs maximum data or endless speeds.
-

-
Top Choice: Skinny 52-Week Endless or Kogan Mobile Extra Large.
Kogan Mobile Plans: 365 Days of Value
When it comes to the annual market in NZ, Kogan mobile plans 365 days of service are often the benchmark. Running on the robust One NZ network, Kogan has built its reputation on aggressive annual pricing.
As of early 2026, Kogan offers four main tiers for their 365-day vouchers:
-
Small (18GB Total): Best for low-data users (1.5GB/mo).
-
Medium (48GB Total): The "sweet spot" (4GB/mo).
-
Large (180GB Total): Heavy usage (15GB/mo).
-
Extra Large (384GB Total): Maximum data (32GB/mo).

Key Considerations Before Buying 🔎
Before you commit your hard-earned cash for a full year, keep these buyer tips in mind:
1. The Upfront Cost vs. Savings 💰
You need the capital (anywhere from $160 to $500) available today. While it hurts your wallet more on Day 1, you won't pay another cent for the next 12 months.
2. Understanding Data Disbursement 📊
Most 365-day plans give you a "monthly allowance" (e.g., 15GB every 31 days). If you use all your data in week one, you’ll need to buy a data add-on or wait for the next cycle. Always check if your chosen provider allows data to "carry over."
3. Network Coverage 📡
Check the coverage in your specific area. Kogan and Mighty Mobile use One NZ, while Skinny uses the Spark network. You can learn more in our mobile networks NZ guide.
How to Switch to a 365 Day Plan
Switching is easier than most people realize and usually takes less than 30 minutes.
-
Check Coverage: Ensure the underlying network (One NZ, Spark, or 2degrees) works well where you live and work.
-
Order Your SIM: Most providers offer free or low-cost SIM cards online or via eSIM for instant activation.
-
Port Your Number: You can keep your existing mobile number. During activation, you'll provide your current account details, and the transfer usually completes within a few hours.
-
Apply Your Voucher: Once your SIM is active, you apply the 365-day voucher code to your account.
