Fibre Broadband in NZ: What Speed Do You Actually Need?

Fibre broadband uses thin strands of glass to transmit data as pulses of light. It's fundamentally different from the old copper phone lines — faster, more reliable, and capable of handling the demands of a modern connected household.

In New Zealand, the Ultra-Fast Broadband (UFB) initiative has brought fibre to over 87% of the population. If you live in an urban area, there's a strong chance fibre is available at your address right now.

NZ ISPs typically offer three main fibre plans:

Fibre 100 (100/20 Mbps) — Download speeds up to 100 Mbps, upload up to 20 Mbps. Handles HD streaming on multiple devices, video calls, and everyday browsing without breaking a sweat. This is genuinely enough for most households of 1–3 people. Note: Fibre 100 replaced the old Fibre 50 tier in June 2025, when Chorus rolled out free speed upgrades across the network. If you were on Fibre 50, you're now on Fibre 100 at no extra cost.

Fibre 500 (500/100 Mbps) — Five times the download speed and five times the upload of Fibre 100. Ideal for 3–5 people, households where someone works from home with large file transfers, or families with teenagers who game and stream simultaneously. This tier was previously Fibre 300 — Chorus upgraded it for free in June 2025, so existing Fibre 300 customers got a significant speed boost without paying a cent more.

Fibre Max / 900 (900/400 Mbps) — The top tier. Unless you're a content creator uploading large files, running a home server, or have 6+ heavy users, you likely won't notice the difference from Fibre 500 in everyday use.

The June 2025 Chorus upgrades were a game-changer for value. Over 700,000 homes got faster broadband overnight, and it means the entry-level Fibre 100 plan is now more than enough for most households.

Here's the honest truth: most New Zealand households are perfectly fine on Fibre 100. The marketing around "ultra-fast" plans often creates unnecessary FOMO.

Consider upgrading to Fibre 300 if: - You have 4+ people streaming or gaming simultaneously - Someone works from home with video calls and large uploads - You regularly download large game updates (50GB+)

Consider Fibre 900 only if: - You're a content creator uploading video to YouTube or similar - You run a home business with significant bandwidth needs - Multiple people in your household work from home simultaneously

Speed isn't everything. Latency (ping) measures the delay between sending a request and getting a response. It matters enormously for gaming, video calls, and anything real-time.

Fibre typically delivers 5–15ms latency within NZ — excellent by any standard. Importantly, all fibre tiers offer similar latency. Upgrading from Fibre 100 to Fibre 900 won't improve your ping in Fortnite.

For comparison: copper VDSL delivers 20–50ms, fixed wireless 15–40ms, and satellite (Starlink) 30–80ms.

Start with Fibre 100. Use it for a month. If you genuinely hit bottlenecks — buffering during peak hours, slow uploads, complaints from the household — then step up to Fibre 300.

Most ISPs, including SpotOn, let you change plans without penalty or lock-in. There's no risk in starting lower and upgrading only when you need to.

Don't overpay for speed you won't use. That $20–30/month difference adds up to $240–360 a year.
