They are getting much better at making their sites look like the original manufacturers, or that they are based in NZ. Drop-shippers can be a good deal, but it is hard to know: you might have no recourse if if there are issues with payment, delivery, service or product.
My first example is http://ainol-novo.com/ - it looks official and sells Ainol tablets, but it is not affiliated with Ainol (ainol.com). Instead it is is run by someone in China. It doesn't have a way to return faulty goods (even though it talks about RMA procedures) and has no way to contact except via a webpage...
A second example is http://www.valuebasket.co.nz/ which makes a good effort to look like it is NZ based (the 09 phone number is presumably a VOIP number?) but the whois information shows it is a drop-shipper run from Hong Kong.
Using whois (http://www.networksolutions.com/whois/index.jsp for .com domains and http://www.loungenetwork.co.nz/whois/ for NZ domains) on either of the above domains shows the actual details.
