New Zealand Refining bounced after Monday's selling, up 2.1 per cent to $2.44. On Monday it announced a pipeline leak had disrupted jet fuel supplies at Auckland International Airport.
"It has bounced back, the impact is going to be around $10 to $15 million on revenue," McIntyre said. "The news is out there now, there are still a few complaining they should have had an announcement on Friday but there are maybe some investors taking an advantage of that pullback in price, noting there's nothing materially wrong with the company and it's just an unfortunate accident."
Air New Zealand dipped 0.5 per cent to $3.20. Its domestic and international flights have been disrupted, as the shutdown is limiting available jet fuel to about 30 per cent of normal usage.
Late today afternoon, the carrier announced it had cancelled further international flights due to leave today, and expected further cancellations. The airline has also stopped all ticket sales on some international services.
Spark rose 0.3 per cent to $3.82 while Contact fell 0.9 per cent to $5.42, Fisher & Paykel Healthcare dropped 1.1 per cent to $12.15 and Vector declined 1.8 per cent to $3.24.
Metro Performance Glass was the worst performer, down 2.9 per cent to $1.02, while CBL Corp fell 1.4 per cent to $2.86. Outside the benchmark index, New Zealand Oil & Gas dropped 1.3 per cent to 74c.
OG Oil & Gas, the oil and gas division of Ofer Global Group, is pursuing a partial takeover of NZOG to keep the local energy explorer's NZX listing and the access to future capital it provides.
The Ofer unit has offered 77c per share for a maximum of 70 per cent of NZOG to trump a rival bid by Zeta Resources.
