married in canada

[Aucknz]

me and my gf met on internet 6 yrs ago .i am currently living in newzealand and she is in canada.we met in person first time in 2007 for few days in india and than i visted usa for two weeks and stayed with her family (they were visting states also).I recently went to canada and got married to her in feb and spent 3 weeks together.Firstly during our relaitionship i never wanted to live in canada because i am living in in nz for 7 yrs and have god job but she doesnot want to come here and wants me to join her in canada.I am going to file outland application in 1 week
Please help me in few questions

I married her in canada on visitor visa.when i applied for canada visitor visa i didnot put in my appl that i am going to marry of visiting my gf.now is there gonna be a problem when i will file for my papers?will they think that i am doing fraud.

i left canada within 3 weeks becoz i have jon in nz and i only got leave for three weeks at that time.i still have 3 yrs multiple visa .so shd i go for outland or go back to canada and apply from there?

if i apply outland and there is interveiw required ,where it will happen becoz there is no CIC in nz .my file will be processed in australia.So do i have to go to australia for interveiw?

Thanks
