Part of the increase it says is due to growing international migration into Whanganui. In 2014, only 63 people migrated to Whanganui from overseas. In 2017, the number had increased to 211 international migrants.
People are earning more as well.
Whanganui's average household income has jumped from $59,300 to $68,300, a $9,000 or 15 per cent increase. Unemployment dropped from above 10 per cent to below 8 per cent over the same period.
"A growing economy is beneficial for everyone in Whanganui as it means there are employment opportunities, increasing money flow for businesses and ultimately leads to more money in the pockets of Whanganui residents," Mr McDouall said.
"This is a clear sign that people are seeing Whanganui as an attractive place to live with an enjoyable lifestyle."
The statistics are publicly available on MBIEs Regional Economic Activity App and Statistics New Zealand's website.
