Low on the horizon from Christchurch
These clear the horizon but stay low, so trees and buildings may hide them: Boötes (~16°, northern) · Lyra (~9°, northern) · Andromeda (~7°, northern) · Cygnus (~4°, northern) · Orion (~2°, eastern) · Taurus (~0°, north-eastern).
Out of reach from Christchurch
At Christchurch's latitude these never climb above the horizon, so you can't see them from here at any time of year: Gemini, Ursa Major, Perseus, Cassiopeia. To catch them, you'd need to travel toward the Northern Hemisphere.
