Meridian’s Strengths
1. 100% renewable generation All electricity Meridian generates is from renewable sources. They operate large hydro stations on the South Island’s Waitaki River system, the Manapouri Power Station, and several North Island wind farms. This is genuine renewable generation — not just certificates purchased to offset fossil fuel use.
2. Market size = competitive pricing As the market leader, Meridian has the scale to offer competitive pricing on standard plans. They’re rarely the absolute cheapest option, but they’re consistently in the competitive range.
3. Wide range of plan types Fixed, variable, EV, time-of-use — Meridian covers the main plan structures for different household needs.
4. Good customer service Meridian consistently rates well in Consumer NZ customer satisfaction surveys. Complaints handling and account management are generally responsive.
5. Strong online account management Meridian’s website and app allow easy usage monitoring, payment management, and plan changes.
Meridian’s Weaknesses
1. Rarely the cheapest As the market leader, Meridian doesn’t need to be the cheapest to attract customers. Independent retailers like Electric Kiwi, Flick, or Frank Energy often offer lower rates on a Powerswitch comparison.
2. No broadband bundling Meridian doesn’t offer broadband services (unlike Contact Energy or Electric Kiwi). You can’t get a power + broadband bundle from Meridian.
3. Break fees on fixed plans If you sign up for a 12 or 24-month fixed plan, leaving early costs money. This reduces flexibility for renters or households likely to move.
Who Is Meridian Energy Best For?
- Households who prioritise a large, reliable retailer with genuine renewable credentials
- EV owners wanting a specific overnight charging plan
- Households that have run the numbers on Powerswitch and found Meridian competitive at their address
- People who value consistency and don’t want to shop around frequently
Meridian vs Competitors
| Feature | Meridian | Electric Kiwi | Flick | Contact |
|---|---|---|---|---|
| Renewable energy | 100% (own gen) | ~80–90% (grid) | Grid mix | ~80–85% (own gen) |

| EV plan | Yes | Yes (Hour of Power) | Yes (spot) | No |
| Contracts | Optional | No | No | Optional |
Verdict
Meridian Energy is a solid, reliable choice for most NZ households. If environmental credentials matter and you want a major retailer rather than an independent, Meridian is a good fit. However, they’re rarely the cheapest option — always run a Powerswitch comparison before signing up to confirm whether Meridian is competitive at your specific address.
Rating: 4/5 — Strong renewable credentials and good service. May not be the cheapest depending on your location.
