This comes on the back of yesterday's share price jump of 9.75 per cent.
Xero's shares have risen 284 per cent in the last year despite the firm having yet to make a profit.
The Wellington-based company announced yesterday that it raised $180 million in new capital, mainly from US investors.
That's left it flush with $230 million in the bank to fund its global growth plans.
The company sold 9.92 million shares at $18.15 apiece, 1.1 per cent above their price last week, to Matrix Capital Management, Peter Thiel-backed Valar Ventures and other US investors.
Today's boost means the new shares have already appreciated 11 per cent.
The sale represents 8 per cent of the enlarged capital of the company and gives it a much wider cash buffer to fund growth as it chases 1 million customers, almost five times its current customer base of 211,000.
Valar and Matrix last injected funds into Xero in November, with $60 million of new capital, while buying $22 million of shares from director Craig Winkler, Drury, and co-founder Hamish Edwards at the same time.
The shares have surged 159 per cent this year, and are more than 20 times the $1 they were sold at in the company's 2007 initial public offer. It is now the eighth biggest domestic company on the local stock exchange.
In June, Xero said its tightly held share register led to a volatile price when the NZX questioned a 23 per cent slide in the stock.
