What is the cheapest One NZ phone plan?

Endless Plus – the new entry point

• After the April 2026 price changes, the cheapest consumer Pay Monthly plan is the Endless Plus at $73/month. This plan includes unlimited data, calls, and texts (One NZ price changes 2026).
• For light users, the Rollover Small prepaid plan at $18/month offers a lower monthly spend but no phone financing eligibility (One NZ price changes 2026).
• Interest-free phone financing requires a Pay Monthly plan of $50 or more, so the Endless Plus easily qualifies (One NZ interest-free phone offers terms).

Prepaid alternatives and MVNOs

• One NZ’s Rollover Small at $18/month is a budget-friendly prepaid option, but it doesn’t support device financing (One NZ price changes 2026).
• Budget MVNOs like Skinny Mobile and Kogan Mobile offer even lower prices (e.g., Kogan Mobile 15GB for $14/month), but they lack the integrated phone deals (Reddit users reporting).

The trade-off: A cheaper monthly bill from an MVNO means buying your phone outright. For many, the interest-free financing on a $73 plan still costs less overall than paying retail upfront.

The implication: light users who stick with prepaid forfeit device subsidies, while heavy users on the $73 plan effectively get a phone discount baked into their contract.

What are the best mobile phone deals in New Zealand?

Interest-free phone deals on One NZ

• One NZ offers interest-free payments on phones priced $199 and above, with a minimum $99 deposit (One NZ interest-free how it works).
• Terms are 12, 24, or 36 months depending on the item (One NZ interest-free how it works).
• On a $50+ Pay Monthly plan, you can save up to $750 over a 24- or 36-month term (One NZ interest-free phone offers terms).
• The One Plan (unlimited data, $88/month) yields savings up to $950 (One NZ homepage).

Current promotions: $1 iPhone 16e

• A limited-time offer from October 2025 to January 2026 gave the iPhone 16e for $1 with a $73+ plan (One NZ dollar deals terms).
• As of mid-2026, it’s unclear if this offer has been renewed. The terms page states offers could be withdrawn earlier.

Comparing One NZ deals with other providers

• Spark’s Pay Monthly plans start at $65/month and offer interest-free financing on selected phones (Spark Phones for Sale 2026: Prices, Plans & Senior Deals).
• Vodafone (now One NZ) has consolidated, making direct comparisons essential.

The pattern: One NZ’s interest-free savings are tied to higher-tier plans. The $73 Endless Plus saves $500 over a 24-month term — but that’s only $20.83/month off the retail phone price. The catch is the commitment to a $73 monthly plan.

Who is offering the best phone deals?

One NZ vs Spark vs Vodafone

• One NZ’s strength is the deep integration of device financing with its Pay Monthly plans. Spark offers similar interest-free deals but often at a slightly higher monthly plan price (Spark Phones for Sale: Prices, Plans & Senior Discounts).
• Vodafone (One NZ) has unified its brand; no separate Vodafone deals remain.

Budget MVNOs: Skinny and Kogan Mobile

• Skinny Mobile’s prepaid plans start at $16/month for 1.5GB, with no device financing (Skinny Mobile official site).
• Kogan Mobile offers 15GB for $14/month (user-reported on Reddit), but device deals are unavailable.

Criteria for ‘best’

• Frequent fliers value One NZ’s global roaming add-on.
• Data-hungry users benefit from the unlimited Endless Plus plan.
• Budget-seekers should combine a cheap MVNO plan with an outright phone purchase.

The catch: “Best” depends on your total cost of ownership over 24 months. A $73 plan with a $500 phone subsidy vs a $14 plan with a $1000 phone — do the math.

The pattern: for frequent travellers, convenience may outweigh cost — but budget shoppers consistently save more with MVNOs and outright purchases.

What are the best new phone plans for 2026?

One NZ 2026 plan lineup overview

• One NZ’s 2026 lineup remains stable: Pay Monthly (Endless Plus, One Plan) and prepaid (Rollover) (One NZ Pay Monthly plans page).
• No major new plan categories have been announced. The April 2026 price changes adjusted existing plan prices (One NZ price changes 2026).

Interest-free financing in 2026

• Interest-free terms still apply to phones $199+. The minimum deposit remains $99 (One NZ interest-free how it works).
• Selected models like the Motorola G06 offer $30 savings over the term (One NZ interest-free phone offers terms).

For 2026, the value proposition hasn’t shifted dramatically. The main change is the price hike on Endless Plus from $50 to $73 — making the entry point to interest-free deals more expensive.

The catch: returning customers who previously qualified on a $50 plan now must pay $73 to access the same device subsidies.

Does One NZ offer global roaming?

Roaming add-ons and coverage

• One NZ offers global roaming as an add-on pack (pay-as-you-go or prepaid packs) (One NZ mobile hub).
• Coverage depends on partner networks; check the One NZ coverage map before traveling.

Costs and data allowances

• Roaming rates vary by destination. As of mid-2026, specific pack prices were not prominently listed on search results; check the official site for current prices.

Alternatives: eSIM and local SIMs

• For cheaper roaming, consider eSIM providers like Airalo or a local SIM at your destination.

For frequent travellers, One NZ’s roaming is convenient but not the cheapest. A $5 24-hour Burst add-on for domestic data is a handy backup.

The pattern: travellers who roam frequently should calculate whether One NZ’s roaming packs beat eSIM alternatives before committing to a plan.

Pay Monthly plans from just $40 per month – that’s how One NZ used to advertise the entry plan. After April 2026, the cheapest pay monthly is $73.

New iPhone 16e is $1 with a $73+ plan – that deal has now ended, but it shows how aggressive One NZ can be.

One NZ dollar deals terms

What this means: One NZ’s phone deals are a trade-off between a low upfront cost and a higher monthly plan. For big data users who would spend $73+/month anyway, the interest-free savings are genuine. For light users, a prepaid plan from an MVNO plus buying a mid-range phone outright will almost always be cheaper over two years.
