As of today (14 September 2021) CLIMsystems is respecting the COVID-19 National Emergency declared by the New Zealand Government and our office is open - with restrictions. All visitors must wear a mask and sign-in using the QR code app or physically sign-in. We will update our status on the next change in COVID level announcement for our region.
