The revelations came amid greater public scrutiny of spending by public officials nationwide, and prompted some council staff in Dunedin to apologise to then-chief executive Jim Harland and repay money.
The latest figures, released last week, showed a handful of cafe meetings and expensive dinners still featured, although numbers were well down on two years ago.
Mr Orders said meetings between council staff had "to all intents and purposes ceased" in the last year.
Each card came with a monthly spending limit, and purchases required receipts, monthly reports and regular checks and approval by each staff member's manager.
Mr Orders said he was satisfied the spending drew on approved council budgets and in the last year, almost without exception, had been for legitimate business purposes.
"There will always be situations around the margin when it comes to areas such as hospitality, but my expectations around this have been made very clear to all staff."
Figures released with the information showed 201 staff had purchase cards in 2010-11, but the number dropped to 173 staff in 2011-12.
Total spending across all cards over the period was $2.59 million, with 6776 transactions totalling $1,346,286 in 2010-11 and 5973 transactions totalling $1,251,818 in 2011-12.
The breakdown of individual transactions covered the top 40 cards, and showed five personal assistants - buying flights, accommodation, stationery and other necessaries for a range of staff - were the highest spenders.
Spending on courses and conferences - as well as associated flights and accommodation - featured prominently in the lists.
However, Mr Orders said in 2011-12 the totals spent were down, and well below budget, compared to the previous year, with about $100,000 of the $328,000 budget unspent in the last year, he said.
The previous year, in 2010-11, council staff had spent $332,000 - about $32,000 more than was budgeted, he said.
Conference spending would be reviewed again while preparing next year's budgets, but it was important staff continued to pursue "appropriate" professional development events, he believed.
He was satisfied staff were operating within proper guidelines, and happy the purchase card system provided checks and balances but also public transparency.
"The position is not perfect, but the figures reveal a significant improvement on what has gone before," he said.
