Unlock Low-Cost Finance for Your Solar & Green Upgrades

Installing solar with Greenco is a smart move — lower power bills, more comfort, and a better future for your home and the planet. But we know the upfront cost can feel like a hurdle.

The good news? Major NZ banks offer special "green" home loan top-ups at incredibly low rates (think 0–1% for several years) to help cover solar panels, batteries, heat pumps, insulation, EV chargers, and more.

At DUX, we help you understand which option fits your situation best, check your eligibility, and get it sorted quickly — so you can say yes to Greenco without the finance stress.

What you'll get

• A clear picture of the green loan options from the major NZ banks - how your bank stacks up, and clarity on all the options.

• Honest advice on what works for your home loan setup, equity, and upgrade plans (solar often qualifies easily).

• Help comparing the banks' offers — some give interest-free periods, others higher limits.

• Simple next steps to apply through your existing bank — we handle the details.

• Confidence you're making a financially smart choice, without pressure or hidden catches.

• No pressure to switch banks just so we get paid more, just the lending you need - unless you want to move banks.

• Confidence a qualified, experienced adviser is looking over your mortgage and can recommend other options for maximising your structure and plan.

No obligation, no jargon — just calm guidance from real advisers who get it.
