Career
Ombler joined the New Zealand National Parks and Reserves Authority (part of the Department of Lands and Survey) in 1975, transitioning to the Department of Conservation when it was formed in 1987. He was a conservator in Whanganui, Hawke's Bay and Auckland, before being appointed as a regional general manager in 1997. While based at Pipiriki on the Whanganui River in the early 1980s, Ombler and his then-wife Kathy co-wrote books about both the river and the Whanganui River Road.

In 2007, Ombler joined the State Services Commission. The following year, he was appointed acting deputy State Services Commissioner, and he was confirmed in that role in 2009.

As deputy State Services Commissioner, Ombler was the interim chief executive officer of the Canterbury Earthquake Recovery Authority (CERA) at its establishment following the 2011 Christchurch earthquake. Ombler returned to CERA as acting chief executive officer on 1 December 2014, taking over from Roger Sutton, and remained in that role until the agency was dissolved in 2016.

In November 2017, Ombler was appointed to conduct an inquiry under the auspices of the State Services Commission into financial irregularities at the Waikato District Health Board. In 2019, Ombler returned as deputy State Services Commissioner on a temporary basis between February and June while a permanent appointee was sought. In June 2019, he carried out an investigation into the actions and statements of chief executive and secretary to the Treasury, Gabriel Makhlouf, regarding unauthorised access to sensitive material related to the 2019 New Zealand budget.

During the 2020 COVID-19 pandemic in New Zealand, Ombler was appointed controller of the all-of-government response and, in that capacity, was a deputy chief executive of the Department of the Prime Minister and Cabinet. He left that role in late 2020.

In April 2021, Local Government Minister Nanaia Mahuta announced Ombler would be a panel member of the Government's independent review of local government.
