I posted this on ozbargain(ozbargain.com.au), but it occurs to me that Kiwis can probably benefit too - get a cheap flight to SYD or MEL or BNE and then grab one of these would make for an incredible price to Vietnam.
Taken with a grain of salt, but I did a quick check with a domestic Vietnam flight and the taxes were ~US$23, so that's not atrocious. Remains to be seen on Monday. Also from the wording, there's probably x on every route where x is a small number, so be fast, I guess.

While the price doesn't include tax and fees, the bargain flights are on offer from 1 January to 22 May, 2025.
The availability of discounted seats on the low-cost airline varies depending on the route and travel dates, the airline points out.
Vietjet flies from Sydney, Melbourne, Brisbane and Perth to destinations including Hoh Chi Minh City, Hai Noi and Da Nang.
Taxes and fees make it pretty much normal price from what I can tell. $850 return from Sydney to Ho Chi Minh, you can score flights from Auckland to Ho Chi Minh for around $1200.
