From having a brief look at their websites - in my opinion yes. They will basically try to monitor for suspicious transactions. I know that in Australia, AUSTRAC treats any transaction over $10,000 as suspicious. Banks must record certain information about parties in transactions above AUD 10K. And as far as I know, if required you must produce adequate documentation supporting that it's a legitimate and legal transaction. This is just in Australia but I'd say it's safe to assume︀ that NZ, UK, and Ireland have that level of security. Especially the UK - England︁ loves their needless red tape and bureaucracy.
