It doesn't look like it is visible from New Zealand. Either that, or I have done something wrong.
That's a shame.

I think you must have something set wrong then as we northern observers lose it after mid December and it shows up in the south if I set my location to Christchurch. I doubt it will reach naked eye the way it is going as comets are rather more unpredictable in their magnitudes. It is also very low for northern observers.

Comet resources:
1. My Comet Chasing page (will be updated on Dec 1)
https://comets.skyhound.com/
2. Select the Current Comets list in the Nightly Planner
Use this tool to determine the visibility of the available comets for your location in a specific night
3. Double-click in a list or use the Designation Search tool to look up "2021 A1" and open the Object Info. The Synopsis tab is particularly useful.
4. Ephemeris tab: select the Nightly Observing Ephemeris, enter the comet, your location, starting now, for a month
This will show you the best nights of visibility during the month on a daily basis

Hi Greg,
I just checked your Comet Chasing web page. It looks like I might have been too optimistic about the visibility of this comet. ST4v thinks it will reach 3.5 magnitude in a few days. Guess we'll see.
Some of the iTelescope folks have been getting images of it. It would be cool to capture an image as it passes M3.
I hope the weather holds up for everyone.

José Chambó's website has a great writeup about the discovery of C/2021 A1 (Leonard) here: Comets visible in November 2021 - Cometography (cometografia.es)
José has taken over for Gary W. Kronk's Cometography website. It looks like a great source of comet information.

Thanks Owen. I had not put my date out far enough.
Thanks Greg
I was (embarrassingly) not aware of that Comets page. it is now in my favorites.

Hi BMD,
Thanks for the links to those teriffic photos. Have you been able to see it?

Phil, I've been out of state 2+ weeks. Had cirrus b4 I left. Back now but Texas is under a blanket until a couple more days. I've not been able to snag a look and it is only up ~23° in the NE at the beginning of astronomical twilight. Only a bit of light pollution there.
