The company issued guidance for a full-year profit of $83m to $85m, saying it expects it to come in at the upper end of that range.
Heartland shares dipped 1c to $1.88 in morning trading.
In its results presentation, the company said the first half result exceeded expectations, particularly due to a much lower than forecast impaired asset expense and continued growth in core portfolios.
However, overall growth was impacted by continued reduction in non-core portfolios and elevated repayments caused by Government and RBNZ stimulus and mortgage holidays allowing customers to divert funds to repay other debt.
"Heartland believes customer repayment activity will normalise, and impaired asset expense levels will be in line with budget for the remainder of the financial year."
Heartland's impairment expense decreased by $4.5m, or 49.7 per cent, to $4.5 million.
The company said this was due to remediation of accounts previously in arrears – largely due to repayments.
It said the financial impact of the Covid-19 pandemic on the New Zealand economy had been more subdued than forecast by major bank economists in the early months of 2020.
Net operating income increased from $118.6 to $125.3m while costs increased $6.5m to $61.1m, reflecting increased staff levels with an additional 78 people in permanent or fixed-term roles compare to the previous corresponding period.
