Clearly you have never imported/exported.
You have 0 chance of success on import/export unless you could pre-sell all the product before paying for it with the supplier.
- You don't have $1000 NZD to spend on product because...
- Port Charges on Import - $240, customs fees, inspection fees, document fees etc for commercial import
- Seafreight Hong Kong - 3 weeks - $200 minimum + the above charges
- GST + Duty (Pretend you're luck and the item doesn't have duty) Payable on Import - Max of $84 given the above spending you need to do to get it in.
- $476 NZD to spend without any spend on marketing or other setup costs
- Fail - Nobody in China will sell you $380USD worth of something that you could make great markup on with fast sell through.
Additionally, this sounds like another self-validation post which seems to be the GP norm at the moment - you've already got your $1000 to $10k genius plan "I could easily do it by utilising my existing reputation" so why don't you tell us all about it as you're dying to prove us wrong.
Edit: The other thing is, most sustainable retail margins on sale in NZ are around 50% (eg clothing etc, must less on other industries); this would be before your costs - eg shipping to customer, costs of sales (transaction fees etc) and not including shipping to get it to you.
So you'd make max:
$1000 -> $1500
$1500 -> $2250
$2200 -> $3375
$3375 -> $5062
$5062 -> $7600
$7600 -> $11400 = success as you have gained 10k + your initial $1000 back. This is in 6 weeks. So you need to have instant stock replenishment, and zero costs, as well as finding a banging product to make sure people are buying from you all the time.
