NZ doesnt have much going for it in terms of access to international equities. If you have over $10k USD, you can get an interactive brokers account, their API is a bit rubbish and commissions are normally around $6.00 USD flat. Otherwise Direct Broking via Jardens, commissions are c. $30 NZD per trade. Sharesies are apparently launching international equities later in the year, but they dont offer API access.
Thanks for the response. I was hoping for API access. It is a pity that companies don't expand here when they open an AU branch. That said, I don't blame them as our regulators are very inflexible, I used to love ipredict until it was shutdown.
Sorry for the delayed reply, I wanted to get confirmation from our brokerage team before posting.
Tradier Brokerage (https://brokerage.tradier.com) can open individual accounts for New Zealand residents and API access comes standard with every account (including market data). You can place orders for US-based equities and options and we offer competitive pricing models for all traders.
If you have any questions, you can email service@tradierbrokerage.com or call 980-272-3880.
As mentioned, Sharesies plan to allow US market access: https://app.sharesies.nz/us-equities-register They do seem to have a private API at least: https://app.sharesies.nz/api/fund/list
https://www.revolut.com/en-NZ have plans to expand to NZ, I don't know much about their services though.
