Brown praised big changes which he said gave the company a far better long-term outlook.
"Management have significantly de-risked the portfolio over the last few months by focusing on leasing up the vacant space," he said, citing offices vacated by BNZ in Wellington, Westpac in Auckland's PricewaterhouseCoopers tower and empty floors at 21 Queen St in Auckland.
Net after-tax profit fell from $28.4 million to $20.4 million after rental income was reduced 5.8 per cent when cornerstone tenant Westpac left for Cooper and Company's East Building in the Britomart and AMP sold the Wellington Chews Lane property.
BNZ has also left the Wellington State Insurance Tower and occupancy had dropped to around 89 per cent.
Scott Pritchard, chief executive, said the half-year was good, major re-leasing initiatives were undertaken at the ANZ Centre on Albert St, risk was reduced and an emphasis was placed on long-term earnings security.
Occupancy was now back around 92 per cent, Pritchard said.
Shares closed yesterday up 0.5c at 88c.
AMP said yesterday the real estate scene it operated in was improving.
"The outlook for prime CBD office space has improved in recent months with most research houses now forecasting market rental growth in Auckland and Wellington."
