Trade Me was unchanged on $3.98. Neil Graham, founder of New Zealand's biggest road transport company, Mainfreight, is taking on Trade Me with the launch of a new online auction and classified site, Wheedle.co.nz on Monday.
"I don't think anyone will panic - good healthy competition should be welcomed," said Mark Lister, head of private wealth research at Craigs Investment Partners. "The first mover advantage that Trade Me has managed to achieve creates a tough segment to break into - from a consumer's point of view good luck to them."
Mainfreight shares fell 1.6 per cent to $10.20. The stock has gained about 5 per cent this year.
The decline was led by Goodman Fielder, down 6 per cent to 62c.
Contact Energy rose 1.5 per cent to $5.56.
"Investors are taking a more favourable view on Contact's management team - we keep coming away impressed," Lister said. "The market is just giving them more of the credibility tick."
Sky Network rose 0.2 per cent to $5.08.
"Sky looks reasonably well priced - people are looking to seek the stocks that have underperformed and Sky TV is one of them," Lister said.
Shares in Auckland International Airport rose 0.2 per cent to $2.63 after it had its credit rating outlook upgraded to "positive" by rating agency Standard & Poor's due to a smaller-than-expected spending programme to cope with congestion at its domestic terminal. The stock has gained about 5 per cent this year.
"It doesn't make a huge amount of difference from an investor's perspective but no one will complain about a rating upgrade," Lister said.
Telecom, New Zealand's largest company, rose 1 per cent to $2.42. Fletcher Building gained 0.15 per cent to $6.68.
The gainers were led by Fisher & Paykel Healthcare, up 2.7 per cent to $2.23.
Shares in NZAX-listed Chatham Rock Phosphate rocketed 30.5 per cent to 30c, their highest since listing in 2006, after announcing it will seek a further US$10 million ($12 million) in a Toronto Stock Exchange listing in the next three months to support its offshore phosphate mining venture, which Edison Investment Research values at $1.87 a share in a new research report.
