Finance Minister Bill English will speak to Australian business leaders just days after announcing Mighty River Power shares will also be listed on the Australian stock exchange.
English's office says his visit today and tomorrow is "part of his regular programme of transtasman engagement".
He will speak to high-level business audiences in Melbourne and Sydney, and meet a number of Australian chief executives and senior business figures.
On Monday the Government said it was confident that between 85 per cent and 90 per cent of Might River Power shares would be held by New Zealanders, including its own 51 per cent stake.
However, English confirmed Mighty River would have a secondary listing in Australia.
