"The thing about beer in NZ ,was the fact that the most expensive and popular beer is bud"
What?? Where were you drinking? At Operation Deep Freeze??
Millers is seni-drinkable and is now reasonably common here because Coca-Cola import it, but Budweiser is considered a light beer here and tastes like weasel's p*ss, so no-one seems to waste their money on it.
You never see Bud in bars here, not even in the bottle fridge with the alco-pops for the ladies. Occasionally it may appear in the specialty beer import shops, but I don't know anyone who buys it. I'd rate it as one of the least popular beers.
Lion Red used to be more popular than it is now. I was a big drinker of it in my youth and still have it occasionally when it's cheap but I discovered about ten years back there are much better brews out there, even NZ made ones.If I have the choice and the cash I fully think the best beer in the world comes from the Trappiste breweries of Belgium. Chimay is awesome for example. But it's a bit too dear for me to drink all the time so I usually drink Speights (which is much the same as Lion Red).
Actually if you're interested in the current kiwi beer market I spotted a link to a story on just that very topic on Radio New Zealand National's site here which you can listen to. I haven't had a listen but you might find it interesting, under the heading Beer Scene:
