To the original post and anyone living abroad looking to move to NZ, there's a financial requirement that the NZ gov't has imposed on brokerage accounts abroad.

As bad as how it sounds like how the US often does by going into other country's affairs. The NZ FMA is doing the same thing by requiring financial institutions abroad to comply to all NZ resident accounts.
One must be aware that when they change their brokerage account to non-resident and declare their residency as New Zealand, being part of retail brokerage, they must conform to the FMA. In many cases, most brokerage firms simply do not want to registered and be licensed. Yes for eg. TD Ameritrade instead of going through conforming with registration and licensing with the NZ gov'ts FMA, they are simply saying to existing and future account holders that they would not provide full services ; specifically in derivative trades (futures, options, and forex). I've been hearing a lot of brokerage firms (including in Canada), that they're simply closing accounts for residents living in NZ. So to the original poster, it's important that who ever holds your RRSPs, or equity investments, that you find out if they are to comply with the NZ FMA? You may find out they don't and will get a nasty situation where they would simply, 'close your account'.
From the link above i'll repost the specifics i'm getting at as some often say my posts are nothing but waffle:
"My foreign exchange broker has just told me they must close my account because of New Zealand regulatory requirements. Why?
Most foreign exchange brokers issue derivatives. If they are offering derivatives to retail investors they must be licensed by us – even if they are making an online offer from outside of New Zealand. Some providers have applied for a licence but others have decided to leave the New Zealand market. This means they cannot accept new retail business from New Zealand and they must close all New Zealand retail customer accounts.
Why can’t I use an Australian regulated, European regulated, or US regulated foreign exchange provider?
You can, but it’s illegal for them to offer derivatives to retail investors in New Zealand without being licensed by us. If they are willing to break the law to get your business, it’s likely they will be cutting corners in other areas and you will have much less protection if things go wrong.
Generally you’ll be a retail investor unless you meet certain criteria, for example, you’re a family trust or you have a large sum of money – in which case you could be considered a wholesale investor.
If you are a wholesale investor, derivatives issuers can continue to deal with you without being licensed by us."
and if you read that statement clearly, it seems there's a double standard for those who have "a large sum of money" and those that trade under a foreign trust scheme. My biggest concern is the next step the NZ Gov't would impose under the FMA is simply requiring all overseas brokers to become licensed - and for which to the point the brokerage firms will simply ignore the NZ market altogether and their clients. This will be the straw that breaks the camel's back for any wealthy migrants having considerable assets in say the US stock market, looking to move to NZ.
