We don't really have buyer's agents in New Zealand (the idea exists but used extremely rarely in my experience).

I'm rather suspicious of the US system that creates a place for two agents getting 3% each for little gain (and a lot of scope for collusion against the buyer and/or seller!)

The New Zealand system has its flaws. The major problem is that vendor real estate agents are financially incentivised to turn over sales as quickly as possible and so smart agents do not represent their vendors properly. I've seen lots of house sales where an offer is made and the agent recommends the seller take it. An early sale costs the agent much less time and they make way more money per year. New Zealanders are generally too trusting, so we get screwed over by people that take advantage of that.
