She said it was an eye-opening experience, revealing an overwhelmed hospital with staff doing their best under trying conditions.
"It was just chaos really because the ambulances just didn't stop coming in so there were people coming in through the night.
"The ambulance crew were fantastic, they stayed beside each of the patients with the trolleys they had and it was just piled up with patients," she said.
While her father eventually got the treatment he needed, and she said his story had a positive outcome, the woman feared what effects the delays were having on others.
"There was a woman, an elderly woman beside me. There was no ward for her to go to and she was physically ill - I had to help look after her because there was nobody to look after her.
"I had found a cupboard that had facecloths in it and was able to wipe her down but there was no towels - there was no resources - and it felt like they were just running on a shoestring."
Referrals being declined - GP
A Wellington GP, who also did not want to be identified, said the emergency department struggles were symptomatic of the struggles the whole health system is facing.
"There's no beds, referrals that we're sending through are being declined. Even when patients are in the system and they've been seen by a specialist they're not followed up with it. Referrals for imaging aren't getting done on time. If they do get listed for surgery they wait months and months."
But she said the situation hadn't come out of the blue - and had been building for months.
"At least the past year, but particularly the past six months, it's getting worse and worse."
Quick fix unlikely - senior doctor
Australasian College for Emergency Medicine president Dr John Bonning said some ED shifts were functioning with only two-thirds of their normal nursing staff.
Yesterday he met with Health Minister Andrew Little to lay out the issues.
While he said the minister didn't make any promises, Little was engaged and wanted to fix the system.
Dr Bonning said there were discussions around possible quick gains to be made with improved processes, but any quick fix was unlikely.
"We are coming up to winter. There's unprecedented levels of burnout and staff illness in the sector. There is potential for this winter to be not very pleasant with seasonal illness and a bit of Covid thrown in.
"It does have the potential to get worse before it gets better."
Little has confirmed there will be a delay in the rollout of the flu vaccine as the provider was unable to supply it for 1 April - the typical start date.
He said the programme will now begin on 14 April.
