The key figures at a glance:

What prepaid plans does Spark have?

Spark currently offers four main prepaid value packs, each valid for 28 days (not a calendar month). All include unlimited texts to NZ and Australian numbers, a set number of minutes, and a data allowance that rolls over if you renew before it expires. Here’s the lineup:

Four plans, one pattern: more data and minutes as you pay more, with the $40 plan as the only one with unlimited calls.

The implication: prepaid works best for users who keep within the data caps; those who stream heavily should compare postpaid options.

What are the different value packs?

Each pack is named by its price point. The cheapest is the $18 pack with 1GB data and 100 minutes. The most popular is the $23 pack, which reviewers at Canstar note offers good value with 2GB rollover data. The $40 pack adds unlimited minutes for those who call often.

How much data do they include?

Data allowances range from 1GB on the $18 pack to 4.5GB on both the $28 and $40 packs. The $23 and $28 packs include rollover data – unused data carries over if you top up before the 28 days expire. The $40 pack also has rollover but at the same 4.5GB cap.

What is the cost of each plan?

Prices are fixed at $18, $23, $28, and $40 per 28-day cycle. Canstar’s cheapest plans list also shows a $15 Spark prepaid plan (1.5GB, unlimited calls/texts) that works out to about $13.59 per 31 days on an annualised basis (Canstar cheapest mobile plans). This plan is not prominently listed on Spark’s site, so it may be a limited or legacy option.

Does Spark offer a discount for seniors?

Yes, Spark has a specific plan for customers aged 65 and over: the Spark Gold Plan. It offers a 20% discount on the monthly plan price. The discount applies to pay-monthly plans, but its availability for prepaid is less clearly documented.

The implication: if you’re 65+ and want the steepest discount, the Spark Gold Plan (20% off) is the best deal, but you’ll need to opt for a pay-monthly plan. Prepaid customers may not qualify, though Spark has not explicitly ruled it out.

What is the Spark Gold Plan?

The Spark Gold Plan is a pay-monthly mobile plan with a 20% discount for customers aged 65 and over. It includes unlimited calls and texts to NZ and Australia plus a data allowance that varies by base plan. You must provide proof of age (such as a driver’s licence or passport) when signing up (Canstar).

How to get a 20% discount for seniors?

To get the 20% discount, you need to be a Spark customer aged 65+ and switch to a Spark Gold Plan. Call Spark or visit a store to enquire. The discount is applied to the base plan price, so a $43 3GB Endless plan would become $34.40 per month.

What perks do you get at age 65?

Beyond the 20% discount, seniors also may be eligible for a $10 monthly discount on pay-monthly plans through the SuperGold card programme, as noted by Canstar. Spark also partnered with Age Concern Canterbury to offer a $10 discount on unlimited plans for over-65s (Age Concern Canterbury). However, these offers are pay-monthly, not prepaid.

What is the cheapest Prepaid mobile plan?

Spark’s cheapest current prepaid plan is the $18 value pack, which gives you 1GB data and 100 minutes. That’s the entry point. But there are a few wrinkles if you’re looking for absolute minimum cost.

Is the $18 plan the cheapest?

Yes, according to Spark’s official prepaid page (Spark NZ), the $18 pack is the lowest-priced option. However, Canstar’s analysis lists a $15 Spark prepaid plan (1.5GB, unlimited calls/texts) that works out to about $13.59 per 31 days. That plan is not prominently advertised on Spark’s site, suggesting it may be a legacy plan or a bundle. If you can find it, it’s cheaper per day than the $18 pack.

What about the $9 plan?

Spark previously offered a $9 prepaid plan with 500MB data and 50 minutes. As of 2025, that plan appears to be discontinued. No official source confirms its availability. The $18 plan is the new floor.

How does Spark’s cheapest plan compare to Vodafone or 2degrees?

Vodafone’s cheapest prepaid plan starts at $19 for 1GB data (as of early 2025, Vodafone NZ). 2degrees has a $15 prepaid plan with 1.5GB data (2degrees NZ). So Spark’s $18 is competitive but not the absolute cheapest among major NZ carriers.

The pattern: Spark’s entry price is low, but data per dollar is not the best among all carriers.

Which is better, Spark or Vodafone?

Both Spark and Vodafone offer prepaid plans starting around $18–$20, with similar call-and-text allowances. The differences come down to coverage, data perks, and customer service.

Two carriers, two philosophies: Spark leads in coverage experience according to Opensignal’s 2022 report, which ranked Spark first in New Zealand for coverage experience. Vodafone counters with faster 5G speeds in urban areas, but its rural coverage is weaker.

The pattern: Spark edges out for coverage and data rollover, while Vodafone offers slightly faster 5G in cities. The Spotify perk on Spark is a nice extra for music lovers.

What is the downside to a prepaid phone?

Prepaid plans have clear advantages (no contract, no credit check, easy top-up), but they come with trade-offs that can surprise new users.

What are the limitations of prepaid plans?

• No unlimited high-speed data: once your data cap is hit, speeds slow down or you pay casual rates ($1 per 10MB per day on Spark, Spark support).
• 28-day cycle, not monthly: you’ll need to top up 13 times a year, not 12. MoneyHub notes that Spark prepaid plans are 28-day products (MoneyHub NZ).
• No bundling with broadband: Spark postpaid plans can be bundled with home internet for savings – prepaid cannot.

Is prepaid cheaper in the long run?

For light users (under 2GB/month), prepaid is almost always cheaper than the cheapest postpaid plan ($43 for 3GB). But if you use 4GB or more, postpaid may be cheaper per GB. The 28-day cycle also means you pay slightly more per year than a monthly plan with the same price.

What about data speed throttling?

On prepaid, once you use your data allowance, Spark throttles speed to a very low rate or stops data entirely. Casual data offers 10MB per $1 for the day, which is expensive. A careful approach: buy a bigger pack than you think you need to avoid extra charges.

The catch: prepaid suits people who use under 3GB per month and want no contract; heavier users should compare total cost with postpaid before assuming it’s cheaper.

Steps to choose the right Spark prepaid plan

1. Check your typical monthly data usage (last 3 months’ phone bill).
2. If under 1GB: $18 pack is enough. If 1-2GB: $23 pack with rollover gives a buffer. If 2-4.5GB: $28 pack is best. Over 4.5GB: consider postpaid or the $40 pack (which has same data but unlimited minutes).
3. Consider whether you need rollover data – if you often have leftover data, the $23 or $28 pack saves unused GB.
4. If you’re 65+, check if you qualify for Spark Gold Plan (20% off) – but note it’s for postpaid only. Prepaid seniors may miss out.
5. Top up via Spark’s website, app, or at any retail store. Set a reminder for 28 days to avoid losing unused data.

Clarity: what’s confirmed and what’s uncertain

What industry observers say

“Spark’s $23 prepaid plan offers good value with rollover data and competitive pricing.”

— Canstar New Zealand, mobile phone review (source)

“Spark prepaid plans are 28-day products rather than calendar-month products, which means you need to top up 13 times a year.”

— MoneyHub NZ, Spark review (source)

For NZ consumers who use less than 3GB of mobile data each month and prefer no contract, Spark’s prepaid plans offer a solid entry point. The $23 pack with rollover data is the sweet spot for most. Heavy users and those over 65 should check postpaid options with senior discounts before committing to prepaid. The decision is clear: light users, go prepaid with Spark; heavy users, look at postpaid or a competitor with bigger data allowances.
