Parker will also end up working closely with NZ First newcomer and former Labour minister Shane Jones, who picks up ministries for Forestry, Regional Economic Development, and Infrastructure.
The coalition agreement announced yesterday included a commitment to spend up to $1 billion a year on regional development initiatives and a plan to plant one billion trees to underpin a new focus on the forestry sector, regional employment, and the creation of carbon 'sinks'.
Ardern's ministry carves responsibilities for the primary sector in agriculture, which goes to long-serving former Labour minister Damien O'Connor, while Stuart Nash becomes Minister of Fisheries, and Jones takes forestry.
She signalled that would require a splitting up of the Ministry for Primary Industries, which the previous National Party-led government had created from the old Ministries of Agriculture and Forestry and the Ministry of Fisheries.
While there has been speculation the new government might also seek to break up the Ministry for Business, Innovation and Employment, Ardern said that any plans for changes at the super-ministry had not yet been formulated.
Ardern herself takes a new position as Minister for Child Poverty Reduction, which will have its own unit established in the Department of Prime Minister and Cabinet and will devise national indicators to measure progress in reducing current levels of deprivation among children, based on Ardern's own Private Members' Bill from the last Parliament.
As expected, Grant Robertson takes the Finance portfolio, with Parker, Jones and Shaw as associate ministers, while Phil Twyford takes the newly reinstated Housing portfolio, which is combined with Urban Development, with Labour's Jenny Salesa taking the Building and Construction portfolio.
Twyford also becomes Minister of Transport, with his responsibilities making him responsible for two of Labour's flagship policy areas: a massive affordable housing construction push and investment in light rail in Auckland.
Leading the new government's policies to strengthen unions' bargaining power and its intention to shrink total migration numbers will be Iain Lees-Galloway, who becomes Minister of Workplace Relations and Safety, along with holding the Immigration portfolio.
Education goes to long-time spokesman in the area, Chris Hipkins, who will also be Leader of the House, assisted by Willie Jackson, who will be a minister outside Cabinet serving as Minister of Employment, which includes the tertiary education, skills and employment portfolios.
David Clark becomes Minister of Health, while Carmel Sepuloni picks up Social Development, where Ardern said she would be undertaking a review of the previous government's "social investment approach" to ensure that it was delivering the improvements claimed for it and was consistent with Labour's "beliefs and values".
Maori affairs are split between three Ministers, with Kelvin Davis taking a new portfolio of Minister of Maori/Crown relations, intended to move policy-making into a post-Treaty settlement mode, while Nanaia Mahuta becomes Minister for Maori Development and Andrew Little becomes Minister for Treaty Negotiations.
The former party leader also becomes Minister of Justice, for Courts, and takes responsibility for the government's intelligence agencies, although Ardern retains the Minister for National Security and Intelligence portfolio routinely held by Prime Ministers.
She will also take the Arts and Culture portfolio, emulating her former boss and Prime Minister Helen Clark, who leveraged the portfolio to strong political effect.
Davis takes another glamour portfolio by becoming Minister of Tourism, while Robertson leavens the dry business of economic management by also becoming Minister of Sport and Recreation.
Megan Woods, who might have expected the climate change portfolio, becomes Minister of Energy and Resources, Research, Science and Innovation, and Minister for the EQC and Greater Christchurch Regeneration.
Peters rounds out his responsibilities by becoming Minister for State-Owned Enterprises, while Nash also takes the Revenue and Police portfolios. Clare Curran takes on the Broadcasting, Communications and Digital Media portfolio, making her responsible for the telecommunications sector.
Defence goes to NZ First deputy leader and ex-serviceman Ron Mark, while fellow NZ First MP Tracey Martin becomes Minister for Children, Internal Affairs, and Seniors.
The commerce and consumer affairs ministries sit with Labour's Kris Faafoi, outside Cabinet, while Customs is also outside Cabinet and held by second-term MP Meka Whaitiri.
Peeni Henare, as Minister for the Community and Voluntary Sector and the Whanau Ora health policy and Aupito William Sio as Minister for Pacific Peoples, round out the Ministers outside Cabinet.
Green Party MP Julie-Ann Genter becomes Minister for Women outside Cabinet.
Each of the three governing parties gains a parliamentary under-secretary.
Rising Labour star Michael Wood becomes under-secretary to the Minister for Ethnic Communities, NZ First's Fletcher Tabuteau has foreign affairs and regional development responsibilities and the Greens' Jan Logie is an under-secretary to the Minister of Justice with responsibility for domestic and violence issues.
