Member of ParliamentEdit
|New Zealand Parliament|
Duynhoven entered Parliament in the 1987 election, winning the New Plymouth seat from incumbent National Party MP, Tony Friedlander. In the 1990 election, he lost the seat to National's John Armstrong, but won it back in the 1993 election. In the 2008 election he lost to New Zealand National Party candidate, Jonathan Young by 105 votes, the smallest margin in the election.
In 2003, Duynhoven raised with the Speaker of Parliament his status, and whether he might have breached electoral law, thus disqualifying him from retaining his seat. The Speaker was responsible for determining whether a vacancy existed. This matter arose after Duynhoven applied to resume his citizenship of the Netherlands. His father was from the Netherlands, and Duynhoven had possessed citizenship from birth, but had temporarily lost it due to a change of Netherlands law. According to electoral law, applying for foreign citizenship would disqualify Duynhoven from retaining his seat. The Speaker ruled on 23 July 2003 that Parliament's Privileges Committee, who were until 2002 responsible for determining whether a vacancy exists, would consider the matter, and that he would be guided by their report. The Solicitor General advised the Privileges Committee that the law was clear, and that Duynhoven's seat became vacant on 11 June 2003. The majority decision of the Privileges Committee was that Duynhoven was disqualified from holding his seat, and that it had accordingly been vacated. However the government introduced an act retroactively amending the law, to allow Duynhoven to resume his seat.
Duynhoven served as a Minister outside Cabinet of Helen Clark's Labour Government with the portfolio of Associate Minister of Transport, and later, Minister for Transport Safety and Associate Minister of Energy until his government's defeat. He did not stand as a party list candidate in the 2008 general election.
Local government politicsEdit
In October 2010, Duynhoven was elected Mayor of New Plymouth. Three years later, on 12 October 2013, Mr Duynhoven became the first New Plymouth mayor since Edward Hill in 1956 to be ousted after one term." 
On 11 January 2015, Duynhoven confirmed months of speculation that he would stand in the upcoming New Plymouth by-election to replace two councillors, John McLeod and Len Howers, who resigned in late-2014. Duynhoven said his decision to stand in the by-election comes after receiving "a huge number of phone calls and visits from people asking me to stand."
On 11 March 2015, Duynhoven made his political come-back and won a seat in the New Plymouth City Ward by-election alongside Roy Weaver after being dumped by voters for another term as Mayor and now is a first time Councillor.
In October 2016, Duynhoven was re-elected to the New Plymouth District Council after being elected to the council in the 2015 by-election and he was elected to the Taranaki District Health Board after the 2016 local elections concluded.
