District manager Nick Pyatt said Remutaka officers were called to help relieve sick leave in the Te Aro.
"Yesterday [Saturday] we had two frontline fire appliances booked off service in Wellington due to staff availability. Like many organisations, we are dealing with higher than normal levels of sick leave at the moment, which is impacting the availability of our personnel.
"We made arrangements to cover these appliances, as is usual when fire appliances are unavailable. This included bringing an appliance from Remutaka Fire Station to Wellington City Station for the day to ensure the city was covered while there were significantly higher numbers of people in town.
"Upper Hutt continued to be covered by Trentham and the neighbouring volunteer stations.
"We continued to respond to all emergencies across the district."
The same day, critical staffing levels at 111 call centres across New Zealand, left empty desks across the northern, central and southern communication centres. At times, just three call-takers were covering all of New Zealand.
Firefighters have said it was not just better wages they were striking for but they were facing burnout from working sometimes 100-hour weeks, had poor working conditions, no mental health support and were driving trucks and using equipment in urgent need of repairs.
Union members began a partial strike on June 13 after 99 per cent of members rejected an offer put forward in April.
Before launching strike action, negotiations had been going on for over a year.
The strike would not yet affect firefighters' response to emergencies, but it would stop members from completing mandatory administrative tasks including gathering statistics, non-essential paperwork, training and attending conferences.
NZPFU was contacted but said it had a mutual agreement with Fenz not to engage with media while bargaining was under way.
