Hi

Im trying to book flights for my family of 5 to Malaysia later this year on the Air NZ website.  Because it is codesharing with Singapore, they wont let me book for more than 4 people on the ANZ website.  Does anyone know anyway around this?  

Could I make 2 separate bookings of say 2+3?

Or just use Expedia (although at the moment that just keeps throwing up a 'we cannot complete your request error 25' at me.

Any ideas?
