Question around NZETA "6 months"

[rektest1]

Awesome thank you, I guess the only thing left is to figure out her 'return flight' to London before arriving in NZ, otherwise they won't let her in the country if she only arrives here using a one-way ticket. I figured if we buy a cheap flight to Australia (with Australian visa) instead of London that should satisfy NZ customs when they ask if she has a flight out of NZ? since you don't need an exit flight when arriving in Australia, according to the embassy website:

There is no requirement to have a return ticket when you arrive in Australia. However officers at the border need to be satisfied that visitors, working holiday maker and temporary residents are intending to and have the means to depart Australia before their visa expires. While not a mandatory requirement, you may wish to carry a copy of your bank statement to demonstrate you have sufficient funds to purchase an airline ticket to depart Australia.

I'm assuming NZ customs won't ask how she's leaving Australia? their only concern would be if she has a way to leave NZ right? i would rather buy a $300 ticket to Australia instead of a $2000 ticket to London :\ because she won't actually be traveling once we are in the interim visa phase and awaiting partnership application, and we aren't keen to spend $2000 for a flight to London that she obviously won't be taking, the ticket out of NZ is purely so they can let her in the country, then we will begin partnership process.

Does this sound feasible or is it too risky? hope this makes sense.

The Immigration Officer at the New Zealand border is entitled to ask how your partner is leaving Australia and request evidence thereof. Ultimately, your partner's ability to return to her country of citizenship is what INZ will be looking for (see E5.10).

I'm a tad confused by that because you don't need a return flight when visiting Australia, according to Australian Government and Embassy website you can visit Australia on a one-way flight, as long as you show (if prompted) enough funds to buy a ticket back home when you're there. According to NZ the rules state as long as you can show an exit flight to a country that will allow you in then you should be fine? would be a waste of money buying a very expensive flight to london that you can only partially (or not even) refund?
