All four seasons were shown on free-to-air TV here in NZ. I remember watching many of the episodes with my girls on Saturday mornings. I rewatched the full series after we got Disney+.
NZs kinda weird though. In the 90s all the American shows and a chunk of their cable TV screened here for free on two channels. Sopranos was free for example.
Often got the best of British and Australian TV.
TVNZ on demand has most of new Trek , Halo, various British stuff etc for free. It's not bad for Sci fi and British comedy.
Not much Canadian stuff unless it was filmed in Canada (eg Highlander, Stargate, Continuum, Warehouse 13).
Trek, Stargate. Babylon 5, Farscape, etc all screened on free TV.
Channel 4 had Sci fi Saturday iirc usually old stuff eg original Battlestar Galactica or dodgy European stuff eg Lexx.
Going back a bit further we were 6 months ro several years behind USA then you might get two or three seasons in a row to catch up eh Simpsons started 1991 or 90210 in 1991.
80s was comparative golden age for NZ content mostly gameshows or travel the provinces type shows. You missed that.
