It may be a 2018 model, but that design was first released for public sale in 2012, and obviously designed before that, so yes, it's a very old design as far as EVs go.

It's not that type 2 is uncommon, or will become uncommon. Type 2 is very common, is a current standand and will be for the forseeable future, however the Zoe uses it in a way that is unique. The bulk of currently available EVs can charge at up to 7kW (32a single phase) or 11kW (16a 3 phase) via type 2 - the constraints are the on board charger capacity, and available supply from the EVSE. Some of the less common Teslas will go to 17kW 3 phase, but in general, 11kW is the best you are going to see. This is quick if you are charging over night, but slow if you are waiting while driving long distance.

The Zoe has a totally different charging system, making use of the traction motor as part of the on board charger, saving weight and additional circuitry. It can charge at up to 43kW (64 amp 3 phase), depending on exact spec. This was it's way of rapid charging. Everyone (almost) else went DC for rapid charging as standards developed, and the network of rapid chargers are all DC. Most NZ ones are 50kW, with a few up to 300 or so and a few historical ones at 25kW. However, the older Zoes can't use the DC chargers, and rely on AC type 2. I'm not aware of any 44kW type 2 around NZ - there's certainly some 22kW (32a 3 phase), but most of the ones at shopping centres etc. are only 32a 1 phase (7kW). So in practical terms, you'll only get 7-22kW charging an older Zoe at public EVSEs in NZ.

It wasn't until 2020 that Renault released a Zoe with CCS (DC) charging, bringing it in to line with other EVs.
