  1. Just think how much stronger the economy would be if all the expat Kiwis returned home, started repaying their loans and also started paying taxes, buying houses, cars and other consumer goods, starting up small businesses, bringing in offshore capital, etc.

    Is this a real call home? Or just a way of stirring up resentment towards those who’ve left and making those who remain feel guilty about leaving?

  2. In the paper, it said that every full-time employee in New Zealand or the equivalent will be paying over $5000 each to rebuild Christchurch, and called for all the expat Kiwi citizens enjoying those nice foreign salaries and not paying their student loans back, to send money home to rebuild Christchurch. quote “What New Zealand needs is a rapid injection of billions from offshore, as a cost to other countries’ economies, and not our own. How is that possible? Quite simply put, there is a $2 billion debt owed by over 85,000 New Zealand-educated citizens, now living overseas, who have outstanding student loans. 35,000 of these Kiwis abroad are behind in their repayment”. They were reminded that there is a 6.6% interest rate on their student loans that they could spare themselves if they pay up to help those left behind.
