What you need are JST ZH connectors. You wont get them in maplin or the likes.
Farnell will have them,

The part number for the terminal is 3357533 about 3 pence each
The part number for the 6 way housing is 3357570 about 10 pence each
Part number for the crimp tool 3357934 about £380
the cheap crimp tools available for servo connectors wont crimp these.
You might be better finding some made up already as above
