Kiwi Maintenance Group has delivered high-quality exterior cleaning to commercial buildings, industrial sites, and institutions across New Zealand since 2010. With 50+ directly employed staff, in-house rope access capability, and ISO 45001:2018 certification, we give Facility Managers a single, reliable contractor who shows up, communicates clearly, and gets the job done without disrupting your operations.
From high-rise window cleaning and building washes to mechanical sweeping, gutter inspection, and rope access cladding work, KMG handles every external surface in-house. No subcontracting. No hand-offs. No re-briefing a new crew every visit. Our directly employed teams know your site, follow your protocols, and return on schedule, year after year. Whether you manage a CBD office tower, a rest home, a school, or an industrial facility, we scale to fit the job.

Every person who arrives on your site wearing a KMG uniform is directly employed by us. Not a subcontractor. Not a labour hire casual. We currently operate with 50+ staff nationwide, all vetted, trained to our standards, and managed through our internal systems. For Facility Managers, this means no surprise faces, no gaps in job knowledge, and no risk of an unqualified crew arriving at a high-value building. It also means consistent quality across every visit, because the same people come back.
KMG holds ISO 45001:2018 certification for health and safety management, a standard many of our competitors cannot claim. We are also Site Wise Gold certified (the highest level from Site Safe), and pre-qualified through both Impac Prequal and CM3. For Facility Managers conducting contractor vetting, this means KMG is already approved. No back-and-forth paperwork. No waiting on compliance documents. Our cloud-based HSE system manages SWMS, toolbox meetings, incident reporting, and SD Sheets in real time via a staff app, giving you immediate visibility when you need it.
Working in occupied buildings, busy rest homes, and operational industrial sites is not the same as cleaning a car park. KMG crews are trained to work around your staff, your tenants, and your schedule. We pre-water gardens before chemical application, cover electrical fittings, manage noise, and coordinate timing around sensitive activities. Our job is to leave your building looking exceptional and your operations undisturbed.
