Can't help with CEA's, but just read today that Emirates is ditching the SYD-AKL sector in favour of more frequency with QF A330's.
Unless some aircraft are in for a rego change, that'll see mainline taking more Tasman flying (back) off Jetconnect.
If this proves just the beginning of Emirates withdrawing from the Tasman.... interesting times ahead.
