He said very low interest rates made the local equities market look attractive because of its high dividend pay-out ratios.
Changes to the tax treatment of property, as outlined in the Budget, had helped to create a more level playing field, and increased KiwiSaver inflows had helped to change the dynamics of the local market, he said.
Stubbs said the New Zealand share market represented just 30 per cent of gross domestic product, but that he expected that statistic to improve.
"We believe that this commodities cycle that we are in will be longer and stronger than some people think."
Increased KiwiSaver flows had allowed Tower to invest in smaller companies, such as Scott Technology and Tourism Holdings - both companies that Tower would not have considered before the scheme was introduced.
Stubbs expected local and international interest rates to remain low for a long time. He said the kiwi remained relatively strong, as did the commodities cycle, and prospects of increased supply in the form of the State Owned Enterprises was a potential plus for the market. Tower would hold funds back if it looked like the Government would proceed with plans to partially privatise the assets.
