All,
We are relocating to Nz by Nov/dec 2015 on Talent visa.
I wish my parents accompany me while moving due to some personal adjustments and hence filing for their visit visa now.

Address : i do not have an address yet to add to application as thier address during stay

Funds : I cant sponsor them as no finance history in Nz. However, my parents can show sufficient funds and so can i in current local currency

Questions
1) is it ok to request for a 6 months multiple entry visa ? Is there a probability of any rejection in such case
2) is it mandatory to show onward ticket while applying visa ? - the problem is my dates are not firm, hence cannot commit on thier dates

Any other tips tht can help prepare thier documentation will help

Please guide

Cheers
