The portal itself is a simple Python cgi-bin, and I wouldn’t be surprised to find it backed by a solid embedded FreeBSD setup (curiousity got the better of me, It’s running an ancient Debian Linux (2.6 kernel), the web server is lighthttp). The captive portal is a short code provided by receipt-printed vouchers, and it’s actually pretty good/reliable as far as these things go. The pricing is tiered, and the best per-MB pricing is 50MB for 10NZD (0.20NZD/MB) – I’m on day 2 and my third voucher right now. I am currently on “Milford Sound Lodge Internet Access” which is a pretty decent satellite connection (about 20KB/s) considering that cell phone reception ended over 100km back (I have a Vodafone and Spark prepaid sims for this trip).

UPDATE: if you are using Windows or Mac and will be on metered Internet, be sure to check out TripMode, an invaluable app for helping you control data usage (Mac users can also try Radio Silence).
