Are there any sellers that can provide insight on large imports and what I can expect and do beforehand? I have always imported within the $1K limit, but now my business is growing and I want to start importing up to $6K at a time. Are large shipments always stopped? How can I make sure everything goes smoothly, do I need a Customs Broker that will clear these shipments? If so, how much do they charge as a rough estimate?

I run a small company and have settled for using the BAC for Trade Me sales and website sales, but would rather find another service that provides best pricing for the website without BAC here. What does everyone else use? I live rural where only NZ Post is an option. Ideally, I'd prefer to do everything elsewhere without BAC so everything is in one place. I have asked NZ Post, but they require large numbers to get discounted rates. Is there another service that uses NZ Post and offers cheaper rates than going direct?
