The New Zealand sharemarket ended the week on a positive note although trading was light, with markets focused on the US fiscal cliff.

The NZX50 index rose 0.06 per cent or 2.66 points to 3957.91. Within the index, 22 stocks rose, 16 fell and 12 were unchanged.

Craigs Investment Partners adviser Greg Easton said trading was somewhat disappointing.

"I thought the US election would take away a layer of uncertain but now everyone's attention has been diverted to the US fiscal cliff so uncertainty prevails," Easton said.

"Volumes were really low and there were no really big movements of any note although Infratil put out the Wellington Airport result and made an announcement about the value of its Europe airport investments."

Infratil fell 0.5 per cent to $2.18 after announcing it recognised an impairment charge of $43.9m for the carrying value of the airports and continued to seek a buyer for them.
