The itinerary included a tour of the Southland Charity Hospital, which is under construction.
When asked her thoughts after walking through the building, she said: "Well, it’s clearly not being built by the Government because it is actually getting done."
It was an indictment on the Government that it had not understood there was an increase in population and increased need in Southland, particularly for colonoscopies.
As the Opposition, they could propose solutions and highlight deficiencies, she said.
Health targets of district health boards mattered and should be focused on.
Speaking about local issues, Ms Simmonds said health services in Southland had been neglected by the Government, as well as the previous Labour-led coalition government.
"When they built a hospital here, that was too small, 90 beds short and two theatres based on the wrong population projections."
This, she said, resulted in the compounding of issues and had not been addressed.
Mr Mooney explained the region was also subject to a post-code lottery when it came to receiving care.
"Southland has the worst bowel cancer rates in the country and New Zealand has one of the worst in the world.
"We’re the worst of the worst but we’re not getting the services we need."
Speaking about the controversial announcement of a proposed $780million cycle bridge in Auckland, Ms Collins said the money should go into roading or solving other matters such as the need for the charity hospital.
"It’s not a nice-to-have here in Southland, it’s a needs-to-have."
However, she doubted it would be built.
Speaking of the 2019 coalition announcement of $1.9billion investment in mental health services, she said National agreed with it.
But nothing had been done.
"It’s worse to promise and not deliver. That false hope given to people is an absolute travesty."
Ms Collins’ visit also included a trip to Winton and speaking with the local farming community to hear about challenges they were facing.
Today, she is to visit the Glenkenich Water Scheme Group and attend a Pomahaka Land Care and Water Group morning tea, and see the Waipahi Wetland.
