You are probably going to want to send more packets before you get an accurate result - obviously if you send two packets and lose one, you get a fail rate of 50%, 4 and lose 1 25%, 8 and lose one 12.5% and so on.

Generally you should get most packets replied to, depending on the reliability of your network, connection, server, hardware, the place you are pinging etc etc. The major thing to look at with ping is the time taken.

Try using ping -t www.yourisp.co.nz and let it run for a while. Use CTRL-C to finish the ping test and display results, or CTRL+Break to display the results whilst leaving the test running.

Once you've pinged your ISP, ping something in New Zealand, and then ping something internationally and compare the results...

The higher the number of packets you send the more accurate the test, however you should get a good idea after about 20 or 30 packets.
