AMP New Zealand Office Trust has boosted its underlying profit by 2.5% as it increased rents and reduced costs.
The listed property investor, which owns 15 office buildings worth $1.3 billion, says distributable profit rose to $60.7 million in the year to the end of June.
Once revaluations are included, it made a loss of $152 million, smaller than last year's $193 million loss.
The trust's acting chief executive, Amish Vallabh, says it is a solid-full year performance given the challenging market conditions.
Mr Vallabh says the Wellington rental market remains robust, but Auckland is proving more challenging.
