I've watched the ISS regularly during evening passes, and previously watched MIR. When there are widespread clear skies and it travels SW to NE along most of New Zealand (which it has been doing since 16 May and finishes doing tomorrow night) I post on the message board at Trade Me, the NZ equivalent of Ebay.
The most recent post:
International Space Station tonight 17 May 2017
The ISS will be visible to the whole country if skies are clear between about 6:47:00 and 6:53:29.
It passes along west of the South Island from 6:49:30 to 6:52:00 then directly above Cape Egmont about 6:52:30 and New Plymouth seconds later, then roughly above Otorohanga, Cambridge, Matamata and Waihi. Goes into Earth's shadow NE of Waihi at 6:53:29.

Unfortunately most of the country clouded over in the early evening, so few saw it. I got three 5- to 10-second glimpses. But it's nice when there are kids outside all over the country, waving to the astronauts. There was nobody to wave to when I saw Sputnik 1, or the rocket which put it up.
I've also watched the ISS on five consecutive passes in one night during two different summers - it only happens close to the summer solstice. The first time was on the night of 29-30 December 2007 at 9:25 pm, 11:00, 12:40 am, 2:12 and 3:48. Second was 27-28 December 2015, maximum height at 10:02:28, 11:38:44, 1:15:51, 2:53:20 and 4:30:34. There was another chance of seeing five passes last November.
Luckily I live under a near-dark sky and often go out to look at the night sky and feel sorry for the northern-hemisphere folk who can't see Omega Centaurii, the two Magellanic clouds, and our other southern wonders. Supernova 1987A was a great naked-eye sight, even with street lights also in sight.
Sometimes I look for and photograph the green flash of the sun as it sets over the Tasman Sea - apparently the green flash is not as rare here as it is north of the equator.
I also look out for the brightest Iridium flares, and have shown nearby kids ordinary satellites when there are five or more showing up within less than ten minutes. The Heavens-Above website makes it easy to see such things.
http://www.heavens-above.comNice daytime shot of the ISS and astronauts over NZ on 14 Dec 2006. I'm at the very top of the picture, just below the topmost coastal forest. Hidden behind a pixel though.
