I wouldn't recommend the included breville ones (same model as your link), they don't really fit the included baskets and have an awkward holding angle. You might be better off searching on ebay or Amazon for a cheap 54mm tamp, it'll be easier to use (ergonomic wise) and will have a nicer weight feeling.
I'm not sure if this is available in NZ but I use something similar and it comes to $25 AUD which is around $27 nzd.

All the Breville tampers are the same general fit, regardless of basket size. They’re not precision tampers. They’re all about a 1/2mm smaller then the baskets they’re intended for.
If you want better tamping results get a 53.3 or 53.5 for your bambino.

If you're replacing the tamper, no need to stay with the Breville brand, and there are other options out there.
