Overall, the NZX 50 Index has advanced 2.5 per cent since the start of the year, outpacing the ASX benchmark's 1.3 per cent rise and the Nikkei 225 Index's 0.2 per cent increase, as investors are lured to the relative high yield of the local bourse and the outlook for the New Zealand economy.
Meanwhile, over the past year, stocks held for their reliable dividend stream have climbed, as investors chased yield investments. The Property Index has gained some 27 per cent, while the Energy Index has soared 52 per cent, also fuelled in part by a post-election bounce which saw the removal of any further regulation in the power market.
The market is starting to reach full valuation, and next month's reporting season will need to justify the recent gains, Williamson said.
"Whether the market has got too many more legs, it's difficult to say but there's still some pockets or areas which still look good value," Williamson said. "We will see a correction at some stage along the way, there's no doubt about that, nothing goes up in a straight line. The good thing with most of the local companies is they have very solid fundamentals."
