I live in New Zealand - born here too.
There have been few truly funny sitcoms made here - in my opinion. The three Good ones were...
- 'Gliding On' (a take off of the civil service here - set in an office - also had a catchy theme tune). Glide Time was the New Zealand phrase for Britain's Flexi-time. Glide time was used a lot in the civil service here in the 70s and 80s. Made in the 70s, maybe very early 80s. Writer Roger Hall still writes some very funny plays.)
- 'Market Forces' (a 90s follow up of 'Gliding on'). Series one was excellent. Series two in my opinion totally lost the plot (literally) and was awful. (Series one had an excellent point - changes that were made in the civl service in the late 80s and 90s).
- 'Letters to Blanchy' was THE BEST sitcom ever made in New Zealand. It was great! Very similar to Only Fools and Horses in a few respects - but defenately not a copy in any way. It ran in the 90s. Very funny. For some reason it's never been put out on DVD though. Although was released on videos in the 90s. Funny acting funny writing. And reflected NZ culture, making fun of it - although the culture might have changed a little since then? Some of the actors did some fantastic TV satire here in the 70s and 80s too. But that was sketch stuff not sitcom.

- Most NZ sitcoms, although there haven't been a lot have been awful.
