The New Zealand dollar and stock exchange have bounced this morning after weekend polls in the UK showed Brexit risk falling.

New Zealand investors should brace themselves for a week of sharemarket volatility as Britain prepares to vote on whether it will leave the European Union.

Norway, Switzerland and Canada are all possible models.

Experts warn a looming vote could spark "the destruction of Western political civilisation".
