I gave my 3yo 6Plus to my daughter, she is happy with it. A new phone = new battery, it has TouchID, yes I think its a good buy. I assume 64GB?

Edit, as in age.

possibly this from JB Hi Fihttps://www.jbhifi.co.nz/features/instant-deals/this-weeks-instant-deal/

I had one as a work phone until recently.  I'm normally very anti-apple but I have to admit this was a very nice phone, did everything I needed a smart phone to do.  Great camera, and the touch ID thing was more useful than I expected

Probably good for iOS12 and then that's it... getting on for 4 years old now... so if that matters to you take into account

Definitely not worth $500.  

I would say the 6 is getting towards end of life as far as usability goes. Not sure i'd buy one new. 

danza: The iPhone 8 is a bit over than 2x the price but performs 3~4x better/faster for CPU/GPU.
The camera, display and pretty much everything else has been improved on too.

I'd say it's not worth it.

The only downside is how long the battery lasts for, as when it ages it will either slowdown or shutdown depending on the power options selected, until you get it repaired with a new battery.

danza: 
Regarding the battery: that's up to the user on how they use their battery. For example it should last for a long time if you dont run down the battery too much everyday, don't let it heat up too much and charge with a lower current / 2.5W charger etc.
.

It really depends on how much you use it from my experience, although yes, not following best practice also isn't good. But some apps and using 4g  alot, will drain it significantly more, and thus increase the number of charging cycles it goes through. Once it reaches a certain number, then it will be considered 'worn' and apple will currently slow it down. but I understand they will  release an update that where the user can either choose for a more unreliable phone, or a slower phone. Current 5s users with worn batteries get a more unreliable phone, but users of iphones 6 and up get a slower phone until they repair the phone with a new battery.

They were still probably manufacturing new iphone 6 models until last year, so the batteries in new ones should be as good as brand new. What is disappointing though, is that apple haven't dropped the iphone 6s price yet to the $500 mark, like they did last year with the iphone 6, and the year prior with the iphone 5s. So this is keeping the iphone 6 price, even second hand, up.

Yeah I would be aiming for a 6s if possible. should be able to get one for around that $ mark. The biggest difference I notice between the 6 and 6s is the extra ram 2gb instead of 1gb. when switching apps on the 6 apps often have to reload from scratch whereas the 6s will resume apps and pages a lot quicker without a reload.

The Warehouse occasionally have factory certified refurbished iPhone6 64Gb for about $500 IIRC. They are effectively 'new' and come with new apple packaging, charger, new Apple warranty etc but not sure about the battery. Would have thought that was pretty good. Just checked and there are none there at the moment.

I got a Galaxy S6 factory refurb from TWH a while back - same sort of thing - indistinguishable from brand new in all regards.
