Yeah, NZ phased ours out late 80s/1990. 2004 we phased out the 5c piece as well.

Anecdotally (as in I might be wrong :) I remember hearing at the time the 5c piece was phased out it was worth less than when the 1/2c pieces were originally released. NB I have put zero effort into thinking if that makes sense or is true. (edit - confirmed)

[ Edit ] - We also made every other coin smaller. It's always startling to get an Australian 50c coin - even though it's the same size as ours used to be. Our's is now smaller than the AU 20c.

I'd say 99% of my transactions are apple pay now, with 1% being rare place that doesn't take paywave. I still have couple buck of cash for those super rare cash purchases on side of the road (damn they need alipay or something like that - NZ is kinda stuck with 'good enough' banking and failing to see innovation from Revolut and the like in Europe - that said surprised how much cash still used in Europe).

>and prices are simply rounded to the nearest 5c when paying with cash

In Canada as mentioned already in the comments we phased out the penny no more made after February 4, 2013.

But many business still today (Oct 2020) have items with prices ending in penny amounts. If you pay with cash it's rounded up or down but if you pay with debit, credit, or cheque the penny amount is used. Stupid because there's no incentive (ha pun!) for businesses to change (double pun!).
