Yeah, I ignore the trading things, and use them as a gateway to the world and as custodians. Agreed on the "4 trades a year" caveat.
They are very cheap custodians compared to many if not most of the NZ options.
Plus they are covered by the Luxembourg/EU bank guarantee schemes, for cash in the accounts not securities in custody, obviously.
They're part of TD Bank of Canada, who keep popping up in the "World's 50 safest banks" tables.
Access to Morningstar research at a global level is useful, too.
