Start a Window Cleaning Business in NZ
TL;DR
The lowest-capital service business after dog walking. A squeegee, a bucket and a website rank you in three weeks. Recurring revenue from monthly commercial contracts is the real prize.

Why this is AI-proof
Streak-free windows are about pressure, technique and angle — none of which an algorithm can do. The customer wants someone they can see do the work and trust to come back monthly. Software has nothing to add.
Two paths: residential round or commercial route
Residential window cleaning is feast-or-famine if you only chase one-offs. The leveraged version is a recurring round — 60-100 houses on monthly or quarterly rotation, $80–$160 per house, predictable cash flow. Commercial is the bigger prize: shopfronts on a route ($30–$60 per shop, 8 minutes each) or office buildings ($300–$1,500 monthly contracts).
Most NZ window cleaners are old-school squeegee operators with no website. A new operator with a fast site, GBP, and suburb pages for their patch can be on page 1 inside a month — and the recurring contract pitch is easier to win when prospects can find you online.

Funding
Three WINZ programmes can stack to help cover this.
If you're on Jobseeker Support, the Self-Employment Start-Up Payment can reimburse what you spend on gear, transport setup, and insurance. Flexi-Wage adds up to NZ$16,800 over 28 weeks of living costs while the round fills. Business Training Grant adds up to NZ$5,000.
Where the demand actually is
Auckland's North Shore + East Auckland (large homes, wealthy demographic), Wellington's hill suburbs (Khandallah, Kelburn, Karori), Christchurch's Fendalton + Merivale, Tauranga's Mount Maunganui and Bethlehem. Anywhere with two-storey weatherboard or brick homes built before 2000 — the windows are large, dirty, and out of reach of a homeowner with a squeegee.
Common questions
Squeegee vs water-fed pole — which should I start with?
Start with squeegees. Master technique on a hundred houses before you invest in a water-fed pole system. The pole becomes worth it once you're doing volume two-storey work or chasing commercial contracts where reach + safety matter.
Do I need to register for GST straight away?
No — only when annual revenue is over $60,000. Most solo operators in year one stay under that. Once you start adding commercial contracts you'll cross the threshold quickly.
Can this scale beyond solo?
Easily. Most established window cleaners run 2–4 person crews with a route booked weeks ahead. The model scales linearly — each extra person adds capacity without adding much cost beyond labour.
