To be honest your options are going to be limited. Domain reselling is kind of a outdated industry practice now. Back in 2008-2013 in the 'golden age of hosting' a lot clients knew they needed to be online but had no idea what that involved, so resellers filled in that void bundling domains with webhosting services. These days there is so much information and guides from customer focused organisations like Wix, Squarespace that they just tell people to buy a domain directly or give them the right information on how to point DNS and let them sort it out themselves. The bottom line keeps going lower and lower with Cloudflare and Google entering the market at cost too.
Honestly as a consumer, just go to Cloudflare and buy gTLD's and for .nz namespace find the cheapest provider possible then transfer it into a premium registrar at no cost. What value does a reseller offer? Nothing really, they just ticket clip and add on a margin and send any issues off the domain registrar. The margins for the domain registrar are also absolute trash; people want 2FA, DNSSEC, customised tooling for the grand total of a $5 PER YEAR margin, whilst fielding multiple queries per year. Soon as you have staff working on a ticket for 15 minutes you just lost your margin for the year. I understand that scalability is a thing but the hosting environment has changed also where if these resellers aren't buying other offerings its a waste of time. So you can see why business have moved away from it and now focus on offering a support model.
