However, Queenstown's marketing body believes there is still plenty of room for growth and wants to boost guest nights in the quieter months between summer and winter to become a resort for all seasons.
The high exchange rate for the New Zealand dollar also means spending by tourists may not be as great as operators would like.
Guest nights rose 9.9% to 2,824,092 for the year ended February 2014, compared with 2013, which recorded similarly strong year-on-year growth on 2012, Statistics New Zealand reported.
The official commercial accommodation monitor for February recorded a 12% increase in international guest nights to 1,858,567 compared with a year earlier, while domestic guest nights rose 6.2% to 965,526.
The average length of stay in Queenstown increased from 2.54 nights to 2.60 nights.
The overall occupancy rate rose from 52.9% to 56.5% and accommodation capacity, excluding holiday parks, rose 2.7%.
Destination Queenstown chief executive Graham Budd said yesterday the statistics were ''pleasing'' and the data supported what regional tourism organisation staff were hearing during the peak summer month of February.
''Last year, 2013 over 2012, we also had an increase of over 10% in guest nights, so this year again is growing on a 10% growth on last year and now we've got growth again.
''Even if we look across the prior months, we've now had well over 12 months of year-on-year growth, so they are really strong results.''
Mr Budd said for the first time the year-on-year results did not include one-off national or international events, which distorted guest night figures. The stable timeframe was showing true, unimpeded and sustained growth, he said.
''Perhaps most importantly, the effects of the GFC (global financial crisis) did hold back markets like the United States for several years and they have really bounced back strongly.''
Mr Budd said a high exchange rate affected the amount of disposable cash visitors had to spend.
''We would hope and expect a lower-valued dollar would turn into greater daily spend and that would be probably the next important variable that would improve even further the current situation.''
All four airlines serving Queenstown Airport have announced seasonal increases in passenger capacity from Brisbane, Sydney and Melbourne.
''I still see a huge opportunity, both domestically and out of Australia, to grow the non-peak shoulder seasons of autumn and springtime, so I think there's a lot of room for growth yet,'' Mr Budd said.
