Give lock on a call and see if they will ship one to you directly.

Note the low down force limit. This is pretty typical for aftermarket towbars.

Note that a DIY tow bar install is pretty involved, and something that it might be best to have done in a workshop. Need to take the bumper off, and in this case cut a hole in it. Often need to drill holes in the boot floor etc too. But no reason you can't DIY if you are up for it.

Normally I prefer dealership towbars on newer cars, but Suzuki doesn't seem to offer one.

Edited, Just did some googling on this NZTA doesnt list much in the way of standards for towbars or fitting them. 

Perhaps its possible to DIY this but i think you wont have much luck unless there is a factory option you can find online to fit yourself. 

The next option is to hit up one of the towbar places and see what they can do, unfortunately there is not going to be a "cheap" option either way.

Only need a engineers certification for tow couplings installs to heavy vehicles.

Rules are surprisingly casual for light vehicles, given the potential consequence's of a trailer separating from a to vehicle at when at speed. 

If you are in range of Wellington I would recommend East Coast Towbars, they did my Mazda 3 for $450 incl electrics 

Blackwells worth a shot too - https://loadmaster.co.nz/ Be careful with the wiring, things have changed from older cars, you can't just use scotch clips to get a feed for brakes/indicators in a lot of modern cars.

Dealer tow bars are a rip off, not essential, and and offer nothing special.  Don't let the dealers fool you.  

There are plenty of aftermarket options that are as good if not better than the dealer products (sometimes from the same factory).  After market providers also have the electronic modules for light wiring to integrate with modern computer systems, and engineering certification so you can have confidence in the bar design and fitting.   

I don't know of any fit-yourself options. IME you would have to be pretty confident in your mechanical capability to fit one to a modern vehicle.  Possibly get one from a wreckers?  

OP doesn't say where they are based.  If in Waikato I can recommend Designer Bars or Pro Bars.  Designer Bars have done both my last 2 new vehicles, including some additional engineering for more down-force for large bike carrier.    

Check with your dealer or Suzuki NZ regarding towing on a 2021 Swift as these vehicles do not have a published tow rating.

Unless its just for a bike rack I wouldn't be using a swift to tow with. Transmission/driveline and rear suspension not setup for this.

Thanks for your replies,  decided to get it fitted locally Tauranga.

My Corolla has a two inch hitch receiver which made me laugh when I first saw it.

I've seen plenty of Leafs with hitches along with a couple of Model 3's with complete bar and ball ... all for bikes...
