Queenstown's Coronet Peak ski field has had a record year of snow, with over three metres falling so far.
This week's southerly blast and subsequent dump of snow has surpassed 2010's snowfall record.
At the opposite end of the country, heavy rain has left over 1000 households without power in the Far North.
Coronet Peak ski area manager Ross Copland said the current conditions in Central Otago were the best the mountain had seen in years.
"We couldn't have wished for a better start to our spring season, we've just broken the 2010 record and we're only 11 days into September."
Mr Copland said September was historically a good snow month, so conditions could get even better.
He said early snow in May and June meant the season started well ahead of recent years, and since then the mountain had been blessed with consistent top-ups.
NZSki chief executive Paul Anderson said spring often offered the best skiiing conditions of the season and this year promised to be the most epic.
"This winter just keeps on giving: we're thrilled we have such awesome conditions for people visiting the mountain."
Queenstown local John Knight said the season of good snowfall had left the town buzzing.
"Conditions up Coronet Peak and the Remarkables have been fantastic and from the start of spring we've had some of the best powder skiing I've ever experienced."
