The harsh truth is hiring in India etc costs around a quarter of a NZ local to do the same job. So either you increase the base cost or introduce a paid NZ number for NZ support or go overseas. Sparks Manilla support is pretty good.
A quarter? You'd be overcharged if it costs 1/10th.
I took the skilled wage(iirc 18000-20000 rupees/mo ~260+usd a month) but yes im still off by a fair bit, maybe closer to 6x.
Indians usually get paid 10 to 20,000 rupees a month at call centres. $1 = 50 Rupees. 20,000 rupees would be a decent paying call centre job = $400 per month. And all of them come with a university education... the job market is THAT competitive in India. However, where they lose out is communication and accent which can be trained by good language trainers.
