Price Creep: Why Your Broadband Bill Keeps Going Up

Nobody wakes up one morning and decides to pay $20 more for broadband. Price creep happens gradually — a $3 increase here, a $5 adjustment there, a "plan restructure" that somehow costs more. Over two or three years, your $69/month plan quietly becomes $85/month.

NZ broadband providers have become adept at incremental price increases. Most are buried in emails you never read or terms you never check. And because switching feels like a hassle, most people just absorb the cost.

The most common price creep tactics in the NZ market:

Annual CPI adjustments ($3–$5/year): Many contracts include a clause allowing the provider to increase prices annually, often pegged to the Consumer Price Index or a generic "cost adjustment." Technically disclosed, but rarely highlighted at sign-up.

Promotional expiry shock: That $59/month introductory rate? It becomes $85–$95/month after 6 or 12 months. The jump can be 30–50%, and many customers don't notice until the bill arrives.

Router rental creep: Your $8/month router rental quietly becomes $10, then $12. Over a 24-month contract, that's an extra $48–$96 you didn't budget for.

Plan restructures: Providers retire old plans and migrate customers to new ones that are "better" but conveniently more expensive. The new plan might include a feature you don't need (like a static IP or premium Wi-Fi management) to justify the higher price.

Removed discounts: Bundle discounts, loyalty discounts, or multi-service discounts that quietly expire without notification.

Let's run the numbers on a typical scenario:

Year 1: $59/month introductory rate = $708 Year 2: $89/month standard rate + $3 CPI increase = $1,104 Year 3: $92/month + router rental increase = $1,140

Total over 3 years: $2,952 What you thought you'd pay (based on the ad): $2,124 Difference: $828

That's $828 more than the headline price suggested — nearly 40% more over three years. This isn't unusual. It's the standard playbook.

The providers counting on you not doing this math. They're usually right.

You're not powerless. Here's what actually works:

Compare annually: Set a calendar reminder every 12 months to compare your current plan against what's available. The market moves fast and new customer deals are always better than loyalty pricing.

Track your actual spend: Don't just look at the monthly rate — check your bank statements for the last 3 months. Include router rental, add-ons, and any fees. Your actual spend is often $10–$20 more than the "plan price."

Call to negotiate: Before switching, call your current provider and ask for a retention offer. Mention specific competitor prices. Retention teams have discretion to offer discounts — but only if you ask.

Switch without guilt: New customer deals are genuinely better. Providers spend more on acquisition than retention because most people don't switch. Be the person who does. The process takes 1–5 days with minimal downtime.

Avoid long contracts: Month-to-month plans cost slightly more upfront but give you the freedom to leave when prices creep. Over 2+ years, the flexibility often saves money.

Here's an uncomfortable truth: the longer you stay with a provider without reviewing your plan, the more you're likely overpaying. The industry calls it the "loyalty tax" — long-term customers subsidise the generous introductory deals offered to new sign-ups.

A 2024 Commerce Commission study found that long-standing broadband customers in NZ paid an average of 15–20% more than new customers on equivalent plans. That's $150–$200/year for the privilege of not switching.

The fix is simple: treat your broadband like your insurance. Review it annually, compare the market, and switch if you're not getting fair value. Your provider isn't rewarding your loyalty — they're counting on your inertia.
